The Ravens elevated Webb from the practice squad to their active roster Saturday for Sunday's contest against the Dolphins.
Webb, an undrafted rookie, failed to make the initial 53-man roster but landed a practice-squad deal at the end of August. With James Proche doubtful (groin), Webb may operate as a depth wideout, but he'll likely have to play on special teams if he's going to make his NFL debut in Week 2.
