The injury was suffered in Week 14 against the Cincinnati Bengals, a game that the Cowboys won, 20-19. Bryant didn't miss significant time due to the injury, as the Cowboys were locked in a playoff battle. Unfortunately for Bryant, the Cowboys couldn't overcome Robert Griffin III and the Washington Redskins and missed the playoffs following a Week 17 loss.
As noted in the report, Bryant actually had his best game of the season after the fracture, when he had 224 yards and two touchdowns in a 34-31 loss to the New Orleans Saints in Week 16.
Bryant had a strong season in 2012-13, and the fact that the injury didn't seem to hamper him much is definitely a good sign. Provided there are no complications with the surgery, it should heal at full strength without issue.
