San Francisco 49ers wide receiver Michael Crabtree has undergone surgery for a torn Achillies, a league source confirmed to ESPN senior NFL analyst Chris Mortensen.
Victor Cruz did not participate in the voluntary practice as he continues to try to work out a long-term extension with the team. But coach Tom Coughlin wasn't thrilled to see his other star receiver, Hakeem Nicks, also absent.
Cutting two games off the preseason -- either by expanding the playoffs or moving to an 18-game schedule -- is still being discussed, commissioner Roger Goodell said Tuesday at the NFL's spring owners meetings.
