Original Text

San Francisco 49ers cornerback Chris Culliver was forced to leave Sunday's Week 1 game against the Dallas Cowboys after suffering a concussion.    

CSN Bay Area's Matt Maiocco has the news:

The 'Niners are in control in the first half against the Cowboys, so getting Culliver back for Sunday's contest isn't a necessity.

Still, San Francisco's depth in the secondary is quickly thinning out, as Tramaine Brock was carted off the field with a toe injury earlier in the game, per Cam Inman of the San Jose Mercury News.
