whitehead was signed as an undrafted free agent by the dallas cowboys after the 2015 nfl draft. he made the team as one of the players that was looked upon to replace the departed dwayne harris special teams production. although wide receiver cole beasley was the assigned punt returner early in the season, because he provided better ball security, whitehead was given opportunities until earning the returner role for the final six games. he only averaged 5.8 yards per attempt as a punt returner, but showed glimpses as a kickoff returner (28.3 yards avg.), like his 79-yard kickoff return against the philadelphia eagles or his key 46-yard kickoff return against the washington redskins to set up the game-winning field goal with 14 seconds left. whitehead was used on offense with special runs designed for him. in the sixth game of the season against the new york giants, he set a franchise record for a wide receiver with four rushing attempts. he finished the 2015 season with 10 rushes for 107 yards and six receptions for 16 yards.
