The Dallas Cowboys will be looking for an extremely important victory tomorrow evening when they take on the San Francisco 49ers at Levi Stadium in Santa Clara, California. The winner will advance to play in the conference championship game for the right to earn a berth in the Super Bowl.

And ahead of tomorrow's game, the Cowboys have announced a roster move. They've signed G/T Aviante Collins to the 53-man roster after he impressed during practice sessions with the practice squad. Additionally, they'll be elevating CB Xavier Rhodes and C/G Brock Hoffman from the practice squad to the 53-man roster.

Meanwhile, they've added TE Peyton Hendershot (hamstring) to the injury report. During tomorrow's game, Jayron Kearse has already been listed as questionable, while LT Jason Peters has officially been ruled out of action. 

Tomorrow's game begins at 6:30 PM EST. Can the Cowboys take care of business and avenge last season's bitter postseason defeat at the hands of the 49ers?
