Broncos cut QB Mark Sanchez

Mark Sanchez, Denver's biggest offseason acquisition, didn't make the roster Saturday, saving the Broncos $3.5 million and a seventh-round draft pick. Sanchez quickly agreed to a deal with the Dallas Cowboys.

The Broncos brought in Austin Davis on a one-year deal to mentor starter Trevor Siemian and rookie Paxton Lynch, neither of whom have ever thrown a pass in the NFL regular season.

Davis was recently released by the Cleveland Browns.

General manager John Elway insisted that Siemian needn't worry about losing his starting job, however.

"He's not going to be looking over his shoulder," Elway said.

The Broncos open the season Thursday night...
