Denver Broncos part ways with fullback Chris Gronkowski, tendered Lance Ball, Colquitt and Clark

Gronkowski had 1 catch for 11 yards last season

ENGLEWOOD, Colo. - Chris Gronkowski became an unrestricted free agent after the Denver Broncos declined to issue a contract tender to the third-year fullback Friday.

The Broncos tendered running back Lance Ball, punter Britton Colquitt and backup offensive tackle Chris Clark. The team would have a week to match any offers the restricted free agents might receive between the March 12-19 signing period.

The Broncos also issued contract tenders to defensive tackle Mitch Unrein and cornerback Tony Carter as exclusive rights free agents who can't negotiate with other teams.

The Broncos obtained Gronkowski, the brother of Patriots star tight end Rob Gronkowski, in a trade from the Indianapolis Colts for defensive back Cassius Vaughn last spring.

Gronkowski had one reception for 11 yards and no rushes last season.
