Cobb had been relatively healthy coming into this season, playing in at least 15 games in four of his five years. His only significant missed time came in 2013 when a broken fibula limited him to just six games.
When healthy, Cobb is still a major part of the Packers offense as a slot receiver who is often a threat in the middle of the field. The 26-year-old hasn't been able to replicate his success from 2014 when he earned a Pro Bowl appearance with 1,287 receiving yards and 12 touchdowns, but he is still one of Aaron Rodgers' favorite targets.
For the season, the receiver has 60 catches for 610 receiving yards and four touchdowns.
Cobb also returned to his former role as a punt returner to get the ball in his hands more often.
"I'm glad to be back there and help the team in any way that I can," Cobb said on Dec. 7, per Wes Hodkiewicz of the Packers' official website. "Just find a way to get different touches and have an impact."
With Cobb out, the Packers needed Jordy Nelson and Davante Adams to continue to step up even more in the passing game. Cobb's return will lessen that burden and give Rodgers another trusted target.
