Raiders place Marcus Mariota on injured reserve

On Monday, the Las Vegas Raiders placed backup quarterback Marcus Mariota on injured reserve with an undisclosed injury. Ian Rapoport of NFL Network reported the 26-year-old has been dealing with a pectoral strain that has limited him during practice sessions:

Per Paul Gutierrez of ESPN, Las Vegas added backup signal-caller DeShone Kizer to the team's practice squad. It's expected that Nathan Peterman will sit behind Derek Carr on the depth chart for Sunday's game versus the Carolina Panthers. 

Mariota, the former starter for the Tennessee Titans drafted second overall by that organization in 2015, was benched in favor of former Miami Dolphins starter Ryan Tannehill last fall. He signed a two-year contract with the Raiders in March. 

Mariota could be eligible to return to the active roster in three weeks.
