NFL-TRAINING CAMPS

Bridgewater throwing...Cruz, Ware back at practice

UNDATED (AP) — Minnesota Vikings quarterback Teddy Bridgewater has resumed throwing with his sore shoulder.

Coach Mike Zimmer has kept up his silence about Bridgewater's status.

Bridgewater threw a few dozen short and medium-length passes in practice Tuesday. It's the first time he's thrown in front of reporters in a week. He didn't play in the preseason game at Seattle. Coach Zimmer has refused to discuss the injury. ESPN.com previously reported the shoulder problem, which Zimmer didn't confirm or deny.

In other training camp news:

— The Giants have welcomed Victor Cruz back to practice after the receiver missed the past two weeks with a groin injury. Cruz is hoping for a comeback after two injury-plagued seasons. He missed last season with a calf injury and had his 2014 season ended after six games by a knee injury.

— Broncos linebacker DeMarcus Ware has returned to practice on a limited basis with an eye on having him ready for the season opener against Carolina. Ware missed training camp with a back issue that kept him out of five games in 2015 but said he feels much better than he did at the end of last season. Quarterback Trevor Siemian didn't throw in practice because of a sore right shoulder. Coach Gary Kubiak said Siemian is day to day but is still the starter for Saturday's preseason game against the Los Angeles Rams.

— Dallas receiver Dez Bryant will miss Thursday's preseason game at Seattle after sustaining a concussion in practice. Coach Jason Garrett says that Bryant was hurt Monday when the receiver's head hit the shoulder pads of safety Barry Church.
