The Bucs have officially placed Cody Grimm on injured reserve, opening a spot on the active roster. That spot, it turns out, will be occupied by tight end Collin Franklin, who is being promoted from the practice squad.

Franklin was a late addition to the training camp roster and immediately had an impressive showing in practice. He becomes the fourth tight end on the roster, joining Kellen Winslow, Luke Stocker and Zack Pianalto. 

Franklin, a rookie from Iowa State, is a receiving threat who led the Cyclones with 54 receptions in 2010.
