The news that the San Francisco 49ers have put receiver Mario Manningham on the injured reserve spurs this question: has Manningham played his last down with the 49ers.Yes, I believe he has.It is not out of the question that Manningham returns in 2014, but I'd say the odds are the team will move on in an attempt to get younger and better depth at receiver. Manningham is a free agent. He signed a two year deal in 2012. He was a solid rotational receiver before tearing his ACL and PCL last December.
