Bills cornerback and return specialist Leodis McKelvin has been placed on injured reserve because of a groin injury.
Buffalo signed linebacker Kirk Morrison back to the team after releasing him on Dec. 3 after he was inactive for 12 games. 30-year-old made 7 tackles for the Bills in 2011 after spending six years with Oakland and Jacksonville.
McKelvin is a former first-round pick in the final year of his contract and eligible to become an unrestricted free agent in the offseason. He set franchise records for punt return yards with 431 this year, giving him the career record at 637. He has taken two punts back for touchdowns this season as well.
