A sprained left knee will keep Buffalo Bills cornerback and kick returner Terrence McGee out of Sunday's road game against the Arizona Cardinals, an NFL source with knowledge of the injury has informed ESPN.com.
The impact of McGee's injury will be lessened by Buffalo's bye in Week 6. He might be able to return to play the San Diego Chargers in Week 7, the source said.
An MRI on Monday confirmed there was no serious structural damage, but the former Pro Bowler was having difficulty moving when he arrived to the Bills facility.
"He's uncomfortable today and not getting around very well," Bills head coach Dick Jauron told reporters Monday afternoon before results of the test were known. "We'll just have to see where this one goes."
McGee was hurt in the first quarter of Sunday's victory over the St. Louis Rams when he got rolled up during a pileup.
McGee is Buffalo's best cornerback and kickoff returner. Arizona has the NFL's fifth-ranked offense and fourth-ranked passing offense. Arizona ranks 10th in points per game.
Rookie Leodis McKelvin, the 11th overall draft pick, will be the likely replacement. He saw his most significant NFL action Sunday after McGee left the game. Ashton Youboty also should see additional time in McGee's absence.
"I would say we'll make any personnel decisions later in the week, but we like both of those guys, obviously," Jauron said. "We've talked about them a lot as the year went on. We'll see what happens, but no personnel things until later in the week."
