Broncos acquire FB Gronkowski from Colts

The Denver Broncos acquired fullback Chris Gronkowski from the Indianapolis Colts on Wednesday in exchange for cornerback Cassius Vaughn.

Gronkowsi appeared in seven games with the Colts last season after spending his rookie campaign in Dallas, in which he rushed for 17 yards and caught seven passes for 35 yards and a touchdown. He is the brother of Patriots tight end Rob Gronkowski and Browns tight end Dan Gronkowski, who played in Denver in 2010.

Vaughn, who joined Denver as an undrafted free agent in 2010, appeared in nine games last season -- three starts -- and tallied 20 tackles with an interception, which he returned for a touchdown.
