San Francisco newcomer Richard Sherman will miss the next week of training camp and the 49ers' preseason opener after straining a hamstring in practice Friday.

"We're definitely going to rest him at least a week  Ty Montgomery Jersey ," 49ers coach Kyle Shanahan said Saturday. "We don't think it should be long term. It's Grade 1, it's a little higher than we expected so we got to be careful with that."

The former Seattle cornerback was hurt chasing down receiver Pierre Garcon after a long completion from Jimmy Garoppolo during a full-team drill. The three-time All-Pro returned to practice at the start of training camp after suffering a torn right Achilles in November with the Seahawks. Sherman signed a three-year $39.15 million deal in the offseason after being cut by Seattle.

In Sherman's place Sunday  Coby Fleener Jersey , the 49ers rotated Tyvis Powell and Greg Mabin with the starting defense. Jimmie Ward stepped in for Sherman during the offseason program but has been withheld from full-team drills after suffering a hamstring strain last week. Ward has participated during individual portions of the last two practices.

San Francisco opens its preseason slate Thursday night at home against the Dallas Cowboys.
