Coach Andy Reid said Fisher would have an MRI to determine the extent of the damage.
Fisher was able to walk off the field after the injury without assistance, though he was favoring the injured ankle. After receiving attention in the Chiefs' medical tent on the sideline, Fisher attempted to walk off the injury.
After a few moments, however, he got into a golf cart and was driven away.
Without Allen and Fisher, the Chiefs went with Donald Stephenson and Jarrod Pughsley as their starting tackles. Stephenson has started 14 games in his three seasons with the Chiefs, and Pughsley has never played in an NFL game.
