CHICAGO -- Cleveland Cavaliers guard Mo Williams flew back to Cleveland following the 123-109 loss Wednesday in Indiana to receive an MRI on his left knee, the team announced Friday.

Williams, who missed a month of game action from late February to late March because of the knee, had only been back in the lineup for seven games before experiencing "discomfort and increased soreness," according to the team, following the loss to the Indiana Pacers.

While MRI results are pending, Cavs coach Tyronn Lue ruled out Williams from his team's last road game of the season Saturday against the Chicago Bulls.

"He tweaked his knee," Lue said. "He's back getting an MRI and just trying to figure out what's going on with his knee."

Williams was diagnosed with chondromalacia -- irritation of the cartilage under the kneecap -- earlier in the season and visited Dr. James Andrews in Florida for a consultation, which resulted in him receiving a platelet-rich plasma injection in the knee.

Williams, who averaged 14.5 points on 49.1 percent shooting and 4.6 assists in 14 starts filling in at point guard for the injured Kyrie Irving at the beginning of the season, has had a limited role lately. Since returning from his month-long hiatus, he averaged 4.5 points on 41.7 percent shooting overall (58.3 percent from 3) in 9.3 minutes per game.

"Just being able to make shots," Lue said when asked what the Cavs will miss in Williams' absence. "He made some big shots for us. Playing with a pace, playing with a tempo and guarding. He did a good job of guarding the basketball.

"It's just unfortunate that he had this problem last game in Indiana."

Lue added that he was still hopeful that Williams would be available to play when the postseason begins next weekend.
