Foster (knee) sustained a knee injury in Sunday's 42-37 loss to the Chiefs, Ed Bouchette of the Pittsburgh Post-Gazette reports.
It remains to be seen whether Foster's current injury is related to the bone bruise he spent the offseason nursing. With Marcus Gilbert (hamstring) also recovering from an injury, Pittsburgh's offensive line enters Week 3 surrounded by question marks. If Foster were to miss any time, B.J. Finney would step in for him at the left guard position.
Foster was diagnosed with a right knee bone bruise after hyperextending the area during Saturday's practice, Jeremy Fowler of ESPN.com reports.

Foster was carted off the field Saturday due to an apparent knee issue, the PIttsburgh Tribune-Review reports.
Foster has started at least 14 games for the Steelers in each of the last seven seasons and was seeking a contract extension with the club entering the final year of his contract in 2018. Unfortunately, the 32-year-old guard's season may have come to a screeching halt Saturday. Bringing out the cart generally signifies a major injury, but it's best to wait until additional test results come in before drawing any conclusions about his status moving forward.
