Broncos sign guard/center to 53-man roster ahead of Ravens game

After using up his practice squad elevations, the Broncos fully promoted offensive lineman Calvin Throckmorton to the 53-man roster.

The Denver Broncos promoted guard/center Calvin Throckmorton from the practice squad to the 53-man roster on Friday, the team announced.

After losing center Luke Wattenberg to an ankle injury, the Broncos elevated Throckmorton from the practice squad to the game-day roster for each of their last three games, which is the maximum number of elevations a player can have in a single season.

With Wattenberg still one week away from being eligible to return from injured reserve, Denver has fully promoted Throckmorton to the active roster so he can serve as the team’s backup center against the Baltimore Ravens behind fill-in starter Alex Forsyth.

Once Wattenberg returns to the active roster (perhaps as early as next week), Throckmorton might be a candidate to get bumped back down to the practice squad.

To make room for Throckmorton on the 53-man roster, the Broncos released veteran fullback Michael Burton on Friday. Burton is expected to re-join the team on the practice squad on Saturday.
