Saturday, Jim Caldwell wouldn't comment about Orr's physical which was taken last month, but he did admit that you never say never as it relates to adding a player who could help.

The longer time goes by without an answer on Orr, the more that seems like the case, especially as the Lions get into camp. Right now, it seems like the team was simply doing their due diligence with the linebacker.

We'll see if that remains the case.
