The San Francisco 49ers have been hit with another big injury.
Defensive back Chris Culliver tore the ACL in his left knee during practice on Thursday and will miss the 2013 season, according to NFL.com. Culliver's injury comes two and a half months after the 49ers lost wide receiver Michael Crabtree to a ruptured Achilles tendon.
Culliver was injured while covering a punt during a non-contact portion of practice. The third-year defensive back was carted off the field with tears in his eyes, according to the San Francisco Chronicle.
The South Carolina-product was a third-round pick of the 49ers in the 2011 NFL Draft.
Besides Culliver, the 49ers are also dealing with an injury to linebacker Patrick Willis. Willis has a slight fracture in his hand that will most likely sideline him until San Francisco's regular season opener.
"You try to dodge bullets. Sometimes you don't dodge them all," coach Jim Harbaugh said when asked about the team's injury situation on Thursday. "But, what it means right now is there's guys that are getting an opportunity to show what they can do."
One of those guys is veteran defensive back Nnamdi Asomugha. Culliver's injury could lead to more playing time this season for the 11-year veteran.
