'Barrington spent the first three seasons of his career with the Green Bay Packers. The linebacker was a seventh round pick of the team in the 2013 NFL draft. He appeared in seven games as a rookie, but ultimately landed on the team's injured reserve. His best season came in 2014 when he appeared in 14 games (7 starts) and recorded 53 total tackles. Barrington was among the Packers' starting linebackers in 2015, but he would suffer a foot injury in Week 1. He'd once again land on the Packers' injured reserve.'
