49ers wide receiver Michael Crabtree had X-rays on his left foot after Sunday's win over the Seahawks. The tests were negative. "It hurt so bad I was concerned," said Crabtree, who was taken out of the game in the second half by coach Jim Harbaugh. Crabtree had a procedure in July to repair a broken bone in his left foot. After missing the first five weeks of 49ers practices, he returned last week and went through three full sessions. He did not start on Sunday, but he was in the huddle on the team's second offensive snap and ended up playing 16 snaps.
