After trainers ran onto the field, Maclin popped up and walked off on his own. He was quickly evaluated on the trainer's table before returning to the game.
Maclin caught a 9-yard pass on his first play back in the game. He led the Eagles with six catches for 43 yards in the first half.
Ins and outs
Cornerbacks Brandon Boykin and Cary Williams were among the seven injured players sidelined. Both have hamstring injuries.
The other inactive players were wide receivers Josh Huff (shoulder) and Brad Smith (groin), running back Chris Polk (hamstring), linebacker Jake Knott (hamstring), and center Julian Vandervelde (back).
Wide receiver Riley Cooper and cornerback Nolan Carroll made their preseason debuts.
Cooper had three catches for 25 yards.
Carroll started for Williams and intercepted a pass. Rookie Jaylen Watkins played slot cornerback in Boykin's spot.
With Smith missing, Jordan Matthews took the first-team snaps as the Eagles' No. 3 wide receiver. Damaris Johnson was the team's top kick returner with Huff out.
Running back Kenjon Barner and kicker Cody Parkey played after arriving in trades on Wednesday. Barner entered the game as a punt returner, while Parkey kicked off and made his only extra-point attempt.
Fourth-year kicker Alex Henery made a 36-yard field goal in the second quarter but missed a 31-yarder in the fourth quarter. He was 3 for 3 on extra points.
Receiver Arrelious Benn left the game with a head injury and did not return.
Bell, Blount play
The Steelers started running back Le'Veon Bell after he and teammate LaGarrette Blount were pulled over by police in Ross, Pa., on Wednesday. Both are expected to be charged with possession of marijuana, and Bell is expected to face a charge of driving under the influence of marijuana.
Bell reportedly paid his own way to fly to Philadelphia for the game; he had 23 yards on nine carries. Blount had 32 yards on seven carries.
Gary St. Ours and John Heffernan debuted as the public-address tandem in the first Eagles home game without Dan Baker on the P.A. system after 29 seasons. St. Ours, who worked with Baker for 17 seasons, handled the football-related calls, such as down and distance. Heffernan handled the marketing and non-game-related announcements.
