Jeff Allen's elbow injury ends his season for the Kansas City Chiefs

Wow, wow, wow. The Kansas City Chiefs season just keeps getting worse. Starting right tackle Jeff Allen's elbow injury will likely end his season, according to Andy Reid. He is having surgery. (Update: The Chiefs just put Allen on IR so his season is definitely over.)

"Jeff Allen is having surgery today on his elbow, his biceps tendon," Reid said after practice Friday. "He'll be most likely out for the season. We'll just see. He's not listed out for the season yet. He is out for this game though.

The Chiefs were already so thin on the offensive line that Allen, a career guard in the NFL, was playing tackle. The Chiefs are down to just two offensive tackles in Eric Fisher and Ryan Harris, who likely start the game at left and right tackle, respectively. Jeff Linkenbach likely becomes the swing tackle in the event of (another) emergency.

This season is turning into something like the 2011 season. The Chiefs were coming off their division title in 2010 and started that 2011 season with three torn ACLs (Tony Moeaki, Eric Berry and Jamaal Charles) and two blowout losses. Derrick Johnson and Mike DeVito were Achilles injuries, and Allen's is an elbow, but this feels an awful lot like that season.

So the Chiefs offensive line includes a No. 1 pick who hasn't lived up to expectations, a left guard who was available to signed in August, a pretty good center, a sixth round rookie at right guard and a journeyman at right tackle. This will be a rough season.

Jamell Fleming, a CB from the Ravens practice squad, takes up the extra roster spot freed by Allen.
