While wide receiver Lee Evans had a full practice today after sitting out yesterday's session because of an ankle injury, three Ravens sat out a second straight practice.
If Grubbs is not able to suit up Sunday against the Titans, Andre Gurode - who was signed by the Ravens 10 days ago - would likely get the start at left guard in Grubbs' place.
The Titans have a few injury issues of their own, as starting defensive end William Hayes (shoulder) was downgraded to no participation today, and starting strong safety Chris Hope (shoulder) missed his second straight practice. Reserve wide receiver Damian Williams (hamstring) also sat out today's session.
Tennessee's No. 2 wide receiver, Nate Washington (not injury related), was limited in today's practice. Defensive ends Jason Jones (knee) and Derrick Morgan (knee) and running back Javon Ringer (back) had a full practice.
