PHILADELPHIA (AP) — Rashaad Penny stayed patient on the sideline, waited for an opportunity and made the most of it.

Penny ran for a career-best 129 yards, including a 58-yard touchdown, Russell Wilson threw one TD pass and the Seattle Seahawks beat the Philadelphia Eagles 17-9 Sunday.

A 2018 first-round pick, Penny has 158 fewer carries than Chris Carson, who is closing in on 900 yards this season.

“It’s been a big test,” Penny said about his backup role. “Just staying poised, waiting my turn and trying to prove I can play but I know I got a great running back in front of me in Chris.”

The Seahawks (9-2) remain undefeated on the road in six games.

Missing their top three wide receivers, leading rusher and two Pro Bowl offensive linemen, the Eagles (5-6) couldn’t do much on offense and hurt themselves with three turnovers inside Seattle territory and another near midfield.

The Eagles didn’t have wideouts DeSean Jackson, Alshon Jeffery, Nelson Agholor, running back Jordan Howard and right tackle Lane Johnson from the start. Right guard Brandon Brooks left the game in the first quarter. Rookie first-round pick Andre Dillard made his first career start at right tackle after playing the left side all season and was benched at halftime.

“I thought we had a good week of preparation, guys were focused,” Eagles coach Doug Pederson said. “That was no indication of the performance today.”

The Seahawks were without star defensive end Jadeveon Clowney.

Philadelphia’s defense did its best to keep it close, sacking Wilson six times.

But Carson Wentz struggled again and the offense was awful. Wentz was 33 of 45 for 256 yards, one TD, two interceptions and lost two fumbles, including one on a handoff exchange.

“I gotta be better,” Wentz said. “No excuses. It starts with me.”

Wilson was 13 of 25 for 200 yards, one TD and one pick.

“I thought we played a great game in a sense that we were able to move the ball extremely well against a really tough defense, one of the top defenses we played this year with all their players, all their schemes and all the different things they do,” Wilson said.
