49ers place CB Nate Hobbs and LB Nick Martin on IR, re-sign S Ashtyn Davis and P Corliss Waitman

The 49ers placed cornerback Nate Hobbs and linebacker Nick Martin on the injured reserve list while re-signing safety Ashtyn Davis and punter Corliss Waitman to one-year deals, per Adam Schefter.

Hobbs and Martin both land on IR, giving San Francisco roster flexibility while the players work to recover. The moves clear two 53-man roster spots, which the 49ers filled immediately with Davis and Waitman. Davis returns to provide defensive-back depth, while Waitman stabilizes the punting job after the team's preseason evaluation.
