Ben Grubbs season is over. The Kansas City Chiefs left guard has been placed on injured reserve which means his season is over.

"With Ben Grubbs, you know that he's been battling this neck problem and we've gone four or five weeks here with rehabilitation (and) he hasn't improved," Chiefs trainer Rick Burkholder said, via quotes from the Chiefs. "So he's going to need at least another month or two to come back from this thing, so with Coach (Reid) and John (Dorsey), we decided as a group to put him on injured reserve. He'll continue to treat with us and we'll give you updates at the end of the season on Ben."

Grubbs suffered a neck injury last month and hasn't played in any games since. It was becoming clear as time went on that injured reserve was a possibility because Andy Reid didn't really know if or when he would be back.

The Chiefs replaced Grubbs with Jeff Allen, which has worked out pretty well so far. Except that Allen is currently not practicing because of an ankle injury. So this week could be a little tight if Allen can't go. Zach Fulton would likely step in at left guard -- assuming he's not playing center. The Chiefs just brought up a center from the practice squad so I'm not sure of the plan there.
