Lions TE Casey FitzSimmons retired on Wednesday after suffering several concussions during his seven-year NFL career, including one in December that is still causing problems.
"This has been a very difficult decision. I feel like 2009 was one of the best seasons of my career, because I was so consistent and was able to contribute in a variety of ways. If it wasn't for the concussions, I would not be retiring," FitzSimmons said in a statement released by his agent, Daniel Hoeven.
The concussion that ultimately shelved FitzSimmons occurred on Dec. 6 against the Bengals. He missed the final four games of the 2009 season on injured reserve and was advised by Lions team doctors to retire.
FitzSimmons, 29, entered the NFL in 2003 as an undrafted free agent and went on to play in 99 games in the NFL. He tallied 88 catches for 677 yards and five touchdowns in his career, including 18-128-0 in ’09.
"Casey is a guy who played the game the way it's supposed to be played," Lions head coach Jim Schwartz said in a statement released by the team. "He was considered an underdog by many, but never by his coaches. He was a guy you could always count on."
