Cowboys coach Jason Garrett confirmed the bone break and said Bryant will undergo surgery. Garrett said the team expects Bryant to miss four to six weeks.
Bryant tweeted Monday night that he underwent successful surgery:
Bryant limped to the locker room in the second half and was not on the field for the Cowboys' final touchdown drive in the fourth quarter. It was the second time Bryant went to the locker room on Sunday night -- he exited the game in the first half due to dehydration.
Bryant finished the game with five receptions for 48 yards on seven targets.
Raw footage taken minutes after the game showed a shirtless Bryant excitedly greeting teammates as they came off the field. He then walked back toward the locker room with a significant limp.
Bryant has been a durable performer since entering the league as a first-round pick in 2010. He played 16 games in each of the last three seasons and has missed just five games in five-plus seasons.
