SANTA CLARA — The pain and tears that washed over cornerback Chris Culliver's face Thursday were different from that of his miserable Super Bowl week in New Orleans. And it signified a growing list of physical challenges for a 49ers team striving to return to the title game.
Culliver sustained a left-knee injury — reportedly a torn anterior cruciate ligament — a day after All-Pro linebacker Patrick Willis fractured his right hand. It's been a growing theme for the 49ers since leading receiver Michael Crabtree tore his right Achilles on May 21.
“There've been some nicks, and we try to dodge bullets,” coach Jim Harbaugh said. “Sometimes you don't dodge them all. What it means now is guys are getting an opportunity to show what they can do.”
While Willis likely will return in time for the season opener from what was termed a “slight fracture,” Culliver's third season is likely done before it starts. He underwent an MRI at Stanford Hospital, and the results showed a torn ACL, according to the NFL Network and ESPN.
Culliver appeared distraught as he climbed onto a cart that took him to the locker room, and general manager Trent Baalke consoled Culliver at one point.
“We wish him the best of luck,” said Perrish Cox, who was the punt returner when Culliver got hurt making a seemingly routine cut as the coverage team's gunner.
Culliver was the team's nickel back last season, playing behind starters Tarell Brown and Carlos Rogers. Culliver also left Wednesday's practice early, because of an apparent upper-body injury.
Culliver was unavailable for comment, and he hasn't granted any interview requests this training camp.
He drew scorn during Super Bowl week for homophobic comments, and he later struggled in the 49ers' 34-31 loss to the Baltimore Ravens.
After Culliver's injury Thursday, Tramaine Brock moved up to the first-string defense and played left cornerback when Rogers shifted into the slot, with Brown at right cornerback.
