Henson, 29, may be running out of chances in his football career. The former Michigan quarterback opted to play baseball in 1998 and signed with the New York Yankees. He played eight games in the majors -- three in 2002 and five in 2003 -- and had one hit in 11 at-bats. He retired from baseball in 2003.
The Cowboys traded for his rights in 2004. Henson had only one start in seven games for the Cowboys.
He signed with the Minnesota Vikings in 2006, and joined the Lions in 2008. Henson threw two passes for the Lions last year, completing one, and had two fumbles.
