The Buffalo Bills activated guard J.J. 'Unga a day after placing him on the active/non-football injury list. Although his injury was undisclosed, it is important for Unga to make a strong impression early in training camp as he faces a stiff battle to earn a roster spot.

Unga played in three games last season, and saw some time with the first team offense down the stretch. But the Bills upgraded the offensive line depth over the offseason and Chris Hairston returns after missing all of last season.
