Coach Mike Tomlin says the team hopes to sign a veteran to replace Batch, perhaps as soon as Saturday.
Tomlin said Batch was hurt on a broken play midway through the second quarter of the Steelers' 16-10 victory.
Batch scrambled for six yards off left tackle after running back Mewelde Moore didn't take a handoff. Batch lowered his shoulder and was hit on the play.
He remained in the game but left after handing off to Gary Russell on the next play with 6:13 left in the half.
