PHILADELPHIA (AP) Nelson Agholor's blunders could send the former first-round pick to the sideline.
The Philadelphia Eagles signed wide receiver Paul Turner off the practice squad on Monday, a day after Agholor had a costly penalty and no catches in a 25-16 loss at Seattle.
Agholor, the 20th overall pick in the 2015 draft, has underperformed in his first two seasons in Philadelphia. He has 50 receptions for 547 yards and two touchdowns in 23 games.

''Sometimes you have to take a step back in order to go forward,'' coach Doug Pederson said . ''Sometimes that can help clear your head.''
Agholor lined up almost 2 yards behind the line of scrimmage and was called for illegal formation to nullify a 57-yard touchdown pass to Zach Ertz that would've given Philadelphia a lead in the second quarter.
Wide receivers coach Greg Lewis and the official nearest to Agholor were signaling for him to move forward, but he didn't see them.
Agholor then dropped a perfect pass 20 yards downfield that would've gone for a long gain. Afterward, he admitted he's thinking about his mistakes .
''I just have to get out of my own head,'' he said. ''I'm pressing so much and worried about so many things.
''Because I'm thinking too much and so worried and it's a selfish thing that needs to stop. I need to give my energy to my teammates and this organization and not myself and feeling so pressured to make every single thing. Just have fun.''
Pederson hinted that Agholor could be inactive next Monday night when the Eagles (5-5) host the struggling Packers (4-6).
''I will definitely have a conversation with Nelson,'' Pederson said. ''Those are definitely concerns that I have, now that he's obviously come out and said that publicly. My concern is for him as an individual, as a person, and I want to make sure that he's in a good spot.''
Turner, an undrafted free agent from Louisiana Tech, was Philadelphia's leading receiver in the preseason. He has spent the first 11 weeks on the practice squad and now gets his chance to prove he should play.
''We gave him some work last week in practice and just feel like this is a good opportunity now, not only for him, but for us to see where he's at, see what he can do and give him an opportunity,'' Pederson said.
On the injury front, the Eagles got mixed news.
Running backs Ryan Mathews is day to day with a mild sprain in his right knee and versatile back Darren Sproles has a nondisplaced rib fracture. Sproles shouldn't miss any games and Mathews likely will be ready to go.
But rookie right tackle Halapoulivaati Vaitai will be sidelined after suffering a Grade 2 sprain of the medial collateral ligament in his knee. Cornerback Leodis McKelvin is in the concussion protocol.
Allen Barbre will move from left guard to take Vaitai's spot and Stefan Wisniewski would replace Barbre. Vaitai has been filling in for Lane Johnson, who returns from his 10-game suspension in four weeks.
NOTES: CB Aaron Grymes was released to make room on the roster for Turner. … TE Brent Celek has played through a similar injury to Sproles. … S Terrence Brooks is expected to return after missing two games with a hamstring injury.
