This offseason, the Lions signed Andre Caldwell with the idea that he could serve as a top pass-catching option behind Golden Tate and free agent pickup Marvin Jones. Unfortunately, he broke a bone in his hand in the summer and the Lions wound up cutting him in August. Caldwell is still looking for work today and it’s possible that he could double back to Detroit. The wide receiver visited with the Lions last week, as Justin Rogers of The Detroit News tweets.

It was initially believed that Caldwell’s injury was a season-ender but between his meeting with the Lions and his recent workout with the Saints, it sounds like he might be ready to return to action. Currently, the Lions have four wide receivers on the roster in Jones, Tate, Anquan Boldin, and Andre Roberts. They’re also carrying three WRs on the taxi squad: Jace Billingsley, T.J. Jones, and Jay Lee.
Caldwell, 31, appeared in 14 games for the Broncos last season, catching 10 passes (22 targets) for 72 yards. While he wasn’t one of the primary targets in Denver, he did also have two touchdowns on the year.
Rogers also hears that defensive backs Sergio Brown, Asa Jackson, Jaiquawn Jarrett, Bacarri Rambo, and Major Wright auditioned for the Lions.
this just shows just how much Megatron will be missed on that team. Calvin was a freak and caught anything thrown his way. Hope you Lions fans enjoyed him. that is what we call a generational player. dont come around often
