In his second stint with the Bears, Booker caught 14 passes for 211 yards and two touchdowns. The Bears were hoping he could be a short-term bridge for their receiving corps, but it was clear his 32-year-old body is starting to break down. A series of injuries forced Booker to miss three of the Bears' last six games, and he caught only three passes in the months of November and December combined.
The Bears have some work to do in order to upgrade the receiver position, but Booker wasn't going to be part of the solution.
The Bears also released linebacker Gilbert Gardner, who played in one game last season, and waived practice squad linebacker Marcus Riley.
