Here are the most significant NFL players who got banged up in Week 2:
Jimmy Garoppolo, QB, New England Patriots: Garoppolo had his right (throwing) shoulder rammed into the turf as he took a big hit from Dolphins LB Kiko Alonso in the second quarter. He walked to the locker room under his own power, but the team announced that he would miss the remainder of the game. Coach Bill Belichick said after the game that the QB is day-to-day, and ESPN NFL Insider Adam Schefter reported the the team hasn't given up hope Garoppolo can play on Thursday night. Garoppolo had 234 passing yards on three touchdowns when he left the game. Rookie Jacoby Brissett replaced Garoppolo in the starting lineup and threw for 92 yards in a seven-point Patriots win.
Adrian Peterson, RB, Minnesota Vikings: Peterson had his right leg rolled up on as he was being tackled by Packers LB Kyler Fackrell late in the third quarter. Peterson, who put no weight on his leg as he hobbled to the locker room, was ruled out for the game. Mike Zimmer said Monday that Peterson tore his meniscus. Zimmer did not rule out Peterson playing on Sunday against the Panthers.
DeMarcus Ware, OLB, Denver Broncos: Ware broke his forearm on Sunday, according to coach Gary Kubiak. He will undergo surgery on Tuesday and miss 4-5 weeks, Kubiak said. The injury occurred when Ware missed a sack of Andrew Luck and slammed into teammate Von Miller instead. Ware walked off the field in visible pain, clutching his arm.
Danny Woodhead, RB, San Diego Chargers: Woodhead tore his ACL at the end of a short reception on Sunday. He will miss the rest of the season. It's the second season-ending injury to a key Chargers skill position player in two games (WR Keenan Allen tore his ACL in Week 1)
Josh McCown, QB, Browns: McCown went to the locker room in the first quarter after taking a shot from Ravens DT Timmy Jernigan. He did not miss an offensive play and said he was "all right" after the game, but on Monday, ESPN NFL Insider Adam Schefter reported McCown will miss the team's Week 3 game versus Miami -- and possibly longer -- as his shoulder injury sounds like something more serious than soreness or a bruise. Rookie Cody Kessler will start in McCown's place.
Doug Martin, RB, Tampa Bay Buccaneers: Martin suffered a hamstring injury early in the second quarter on a 1-yard run against the Cardinals. He did not return. Martin had a tough time finding running room before he left the game with 23 yards on seven carries.
Julio Jones, WR, Atlanta Falcons: Jones, who has been battling an ankle injury since the preseason, limped off the field late in the Falcons' game on Sunday, missing the team's final series. ESPN NFL Insider Adam Schefter reported that Jones suffered a strained calf and the injury is not considered serious.
Thomas Rawls, RB, Seattle Seahawks: Rawls injured his leg in the second quarter against the Rams and did not return. Coach Pete Carroll said his RB got kicked in the leg and had a contusion. According to ESPN Seahawks reporter Sheil Kapadia, the injury does not appear to be serious. Rawls started the game for the Seahawks but lost 7 yards on seven first-half carries. He had his 2015 season cut short when he suffered a broken ankle in Week 14.
David Amerson, CB, Oakland Raiders: Amerson came up with another big interception for the Raiders on Sunday, but he left the game with a head injury late in the fourth quarter. Coach Jack Del Rio said Amerson would go through the concussion protocol.
Donte Moncrief, WR, Indianapolis Colts: Moncrief took a shot to the head from Broncos safety T.J. Ward as he stretched for a pass toward the end of the first quarter. The team diagnosed him with a head/neck injury. Moncrief did not return to the field; ESPN NFL Insider Adam Schefter reported on Monday that the WR would undergo an MRI on his shoulder.
Jonathan Stewart, RB, Carolina Panthers: Stewart entered Week 2 on the injury report because of an ankle injury, and he hurt his hamstring early in Sunday's contest against the 49ers. He missed the remainder of the game, and RB Fozzy Whittaker rushed for 100 yards on 16 carries in his place. According to ESPN Panthers reporter David Newton, Stewart is expected to miss Sunday's game versus the Vikings, maybe longer.
Arian Foster, RB, Miami Dolphins: Foster did not return to Sunday's contest after suffering a groin injury in the second quarter. ESPN NFL Insider Adam Schefter reported that the veteran RB will undergo an MRI on Monday, but the team doesn't think the injury is overly serious, according to a source. Coach Adam Gase called Foster day to day. This is the latest in a recent string of Foster injuries: He entered the week with a hamstring injury, had groin surgery in training camp last season and suffered a season-ending Achilles tear in Week 7 of 2015.
Kelvin Beachum, LT, Jacksonville Jaguars: Beachum took a blow to the head on a freakish play in the fourth quarter. Trainers strapped him to a backboard and carted him off the field. He suffered a concussion on the play. The team announced that Beachum had feeling in his extremities and was being taken to a hospital for further evaluation.
Letroy Guion, DT, Green Bay Packers: Guion suffered a sprained MCL in the second quarter against the Vikings. According to ESPN Packers reporter Rob Demovsky, he could miss a few games, but this is expected to be a short-term injury, as initial test showed no ACL damage.
Doug Baldwin, WR, Seahawks: Baldwin tweaked his knee in the second quarter Sunday, when he was blocking with his back to the line of scrimmage and got his leg rolled up on from behind. He missed two snaps before returning to the game and will undergo an MRI on Monday.
Ezekiel Ansah, DE, Detroit Lions: Ansah hobbled off the field after the third snap of the game. Ansah, who ranked third in the NFL last season with 14.5 sacks, did not return to the game (ankle). It was the beginning of an injury-filled day for the Lions.
P.J. Williams, CB, New Orleans Saints: In a scary situation, Williams stayed down on the field for several minutes after he appeared to take two blows to the head in the first quarter. Trainers strapped Williams' helmet to a backboard before an ambulance took him away from MetLife Stadium. Coach Sean Payton said "all the news is positive," adding that Williams will return home Monday afternoon after he stayed overnight at the hospital for evaluation. Williams -- who was serving as New Orleans' No. 1 cornerback on Sunday, in the wake of the broken fibula Delvin Breaux suffered last week -- was diagnosed with a concussion and will have to pass the league's protocol.
Darius Butler, CB, Colts: Butler intercepted Broncos QB Trevor Siemian in the second quarter and appeared to have a clear path for a pick-six. But Butler, who entered the game with a hamstring injury, hurt his hamstring on the return and did not come back into the game.
Ameer Abdullah, RB, Lions: Abdullah hurt his foot at the end of a 24-yard run in the second quarter. He almost immediately went to the locker room and was eventually ruled out of the game. Abdullah had six carries for 38 yards when he left the game.
Cameron Erving, C, Cleveland Browns: Erving left FirstEnergy Stadium via an ambulance after Cleveland's five-point loss to the Ravens. According to ESPN Browns reporter Pat McManamon, the team said Erving suffered a bruised lung and was released from the hospital on Monday morning, adding, "His return to play status will be evaluated on a week-to-week basis."
Tyler Lockett, WR, Seahawks: Lockett left the Seahawks' game against the Rams late in the second quarter because of a sprained knee, but he returned in the fourth quarter. He finished with four catches for 99 yards.
Kyle Van Noy, LB, Lions: Van Noy suffered an undisclosed injury in the third quarter and went right to the locker room. With Antwione Williams also ruled out for the day, Van Noy's injury left Detroit with two healthy linebackers: Tahir Whitehead and Thurston Armbrister.
