A.J. Tarpley announced his retirement tonight via Instagram because of concussion concerns. The second-year Bills linebacker is the latest player to do so and joins a growing list of young players leaving football early.
A second-year cog expected to see time on the Bills’ second level again this season, Tarpley confirmed he suffered the third and fourth concussions of his career as a rookie in 2015. He joined the Bills as an undrafted free agent from Stanford.
Tarpley started in two games last season and played in 15. The 23-year-old linebacker played mostly on special teams but recorded a sack and made two interceptions, though, one of which he returned for 37 yards against the Cowboys.
He looked set to potentially compete for a starting position after Nigel Bradham, whom Tarpley started in place of last season due to injury, left to join the Eagles.
