I think you got this from PFT. Its misleading the way its written. He was originally signed by Detroit on August 24th. He played this past weekend for Detroit and had a 79 yard TD. Detroit cut him yesterday and today signed him to their practice squad. If the Pats had put in a claim, they would have got him. Detroit already cut him. Instead, I think its more likely they inquired about him joining the Pats practice squad, but he chose Detroit's instead.
