TAMPA, Fla. – The Tampa Bay Buccaneers added some speed for their return game, but also lost a starting tight end Monday.

Former Olympic sprinter Jeff Demps, who had spent the last two weeks practicing with the Bucs while on the exempt list, was activated to the 53-man roster. But the bad news is the Bucs placed tight end Luke Stocker on injured reserve.

Demps, who also may get a look as a running back and receiver, could take over as the primary return man or share the duties with Eric Page.

With Stocker gone for the season, the Bucs are thin at tight end. Nate Byham started in Stocker’s place Sunday. Tom Crabtree has missed the first three games with an ankle injury, but coach Greg Schiano said Monday that Crabtree is making progress. If Crabtree is healthy by Sunday, he could be the starter against the Arizona Cardinals.
