The Washington Redskins cut 10 players Saturday and two more Tuesday to help reduce their roster to 75. Here's a closer look at the first cuts:

Most significant move: Releasing Perry Riley and Stephen Paea. Riley, a fourth-round pick by Washington in 2010, was coming off a foot injury and couldn't beat out linebacker Mason Foster and therefore would have been an expensive backup. His cap hit this season would have been $5 million. Paea, who received a four-year, $21 million contract last offseason, was signed to provide a pass rush but wasn't helping in that area. He was another expensive backup made expendable when the team signed Cullen Jenkins on Monday.

Injury issues: Running back Keith Marshall was placed on injured reserve after hurting his elbow last week. The team said he would miss at least three weeks, but feared he would be out longer and also wanted to find a way to keep him around to develop his speed. He probably wouldn't have made the 53-man roster, most likely losing out to Rob Kelley. The Redskins also placed tight end Derek Carrier on the physically unable to perform list, as expected. Carrier tore his ACL and MCL in his knee last December, so even six weeks on the PUP list would qualify as a quick return.

Linebacker battle: Outside linebacker Willie Jefferson was competing to become the fourth and final player at this spot. Even a week ago he appeared to have an edge on Houston Bates for this role. The Redskins liked Jefferson's length and athleticism, but he was too inconsistent in games. Bates, meanwhile, might lack Jefferson's ceiling but is more ready to play if needed. With Ryan Kerrigan nursing a groin injury, albeit a minor one, the Redskins don't need to risk carrying a player they mostly want to develop for the future.

Redskins moves: RB Keith Marshall (injured reserve), TE Derek Carrier (PUP list), LB Perry Riley, DL Stephen Paea, LB Willie Jefferson, T Al Bond, T Cody Booth, LB Shiro Davis, LB Ejiro Ederaine, CB Jeremy Harris, WR Valdez Showers, WR Dez Stewart, WR Jarvis Turner, RB Kelsey Young and WR Reggie Diggs (waived/injured).
