As the Vikings await word on Teddy Bridgewater's apparently serious leg injury, the team made five moves to reach the roster limit by Tuesday afternoon's deadline.

The most prominent of early moves was the release of veteran center John Sullivan, who had started 93 games since the Vikings drafted him in the sixth round in 2008. General Manager Rick Spielman tried to find a suitable trade partner for Sullivan, but clearly the Vikings didn't get a deal they wanted.

Sullivan's exit frees more than $5 million as his base salary was not guaranteed for the upcoming season. Joe Berger took his place as the starting center Tuesday before practice was called early due to Bridgewater's injury.

The Vikings also waived safety Antone Exum Jr. and defensive tackle Scott Crichton with injury designations. Exum Jr. suffered a left knee injury in Sunday's preseason win against the San Diego Chargers, while Crichton had not practiced in weeks due to an undisclosed injury. If either player goes unclaimed, they'll revert to injured reserve.

Receiver Troy Stoudermire was also waived.

Offensive lineman Mike Harris was moved to the reserve non-football illness list, freeing up another roster spot.

The Vikings roster is now down to 75 players, including Bridgewater.
