If that fear is real, it would likely end his season.
Foster went down in the second half of the game, and was replaced by Kelvin Beachum. Left guard became the fifth position Beachum has played this season, with previous fill-in roles at center, right tackle, left tackle and tight end.
If Foster's injury is confirmed to be that severe, it would seem the Steelers would make a roster move. That possibly could be calling up Joe Long from the practice squad to replace Beachum's tackle versatility. However, considering how much Mike Adams is struggling, it's possible he'll be replaced on his own accord. Veteran Guy Whimper is still a reserve lineman, but the fact he hasn't been used, or even mentioned publicly, as an option to this point could suggest he's merely there as an emergency in-game replacement.
Post-Gazette reporter Ed Bouchette mentioned in his notebook moving Whimper to left guard with Beachum taking over left tackle for the embattled Adams.
The Steelers are 0-4 for the first time since 1968, and have a bye before facing the similarly struggling New York Jets in Week 6.
