49ers CB Richard Sherman had to be helped off the field at halftime with a calf injury.
Advice: His return is officially questionable, but he could not put much weight on his leg on the way into the locker room at halftime. Ahkello Witherspoon replaced him at the end of the first half.
The 49ers have lost star cornerback Richard Sherman to a calf injury, the third defensive back to get banged up in their game against Kansas City.
Advice: Starting safety Adrian Colbert left with a hip injury in the second quarter, and backup cornerback Tarvarius Moore left earlier in the game with a wrist injury. Another starting safety, Jaquiski Tartt, was inactive with a shoulder injury and cornerback Greg Mabin was also inactive. That means the 49ers are severely depleted in the defensive backfield.
Sherman is expected to play Sunday at Kansas City despite being held out of Thursday's practice with a heel injury.
Advice: Sherman's placement on the injury report at first raised some eyebrows considering he underwent surgery last November to repair a ruptured Achilles tendon, but 49ers coach Mike Shanahan said the cornerback's absence was just precautionary. "He's had some wear and tear on his heel ... We're taking it smart with him," Shanahan said.
Richard Sherman (heel) is expected to play in Week 3 against the Chiefs.
Advice: Sherman was absent for Thursday's practice but returned Friday and wasn't listed on the team's final injury report. He'll be tasked with slowing down Tyreek Hill and the red-hot Chiefs offense in Week 3.
