DENVER (CBS4) – The Broncos announced Wednesday that they have traded fullback Cassius Vaughn to the Indianapolis Colts.

In exchange, they will get Chris Gronkowski, a fullback.

Football runs in the family for Gronkowski, who is the brother of Patriots star tight end Rob Gronkowski and Dan Gronkowski, a tight end with the Cleveland Browns. Dan Gronkowski played for the Broncos as a tight end in 2010.

Vaughn suffered a broken leg during the Broncos game in San Diego last November. He played for the Broncos in both the 2010 and 2011 seasons, playing in 22 games and making 22 tackles and returning an interception for a TD.

“Our team has a lot of depth in the secondary and this is an opportunity for us to add a quality fullback to our roster,” said Broncos executive John Elway on his Twitter page.

The only other fullback in Denver is Austin Sylvester, who hasn’t played in the NFL.

While Chris Gronkowski and Peyton Manning were on the Colts together last year, they never played together on the field since Manning was out with his injured neck all last season. Gronkowski played for the Cowboys during the 2010 season.
