The Chiefs suffered another blow to their starting lineup on Friday when offensive right tackle Jeff Allen underwent surgery to repair the bicep tendon in his elbow. He is out for the season.
Allen was placed on injured reserve, and the Chiefs filled his spot on the 53-man roster by claiming cornerback Jamell Fleming from Baltimore’s practice squad. Fleming entered the league as Arizona’s third-round pick from Oklahoma in 2012, and he spent 2013 with Jacksonville.
The Chiefs already have lost inside linebacker Derrick Johnson and defensive end Mike DeVito to season-ending Achilles’ injuries and inside linebacker Joe Mays for at least six weeks after undergoing wrist surgery.
Also, rookie running back/kick returner De’Anthony Thomas will miss Sunday’s game at Denver with a strained hamstring.
Allen, a two-year starter at left guard, was playing right tackle in place of Donald Stephenson, who is serving a four-game suspension for violating the NFL’s substance abuse policy.
