Alshon Jeffery

Jalen Reagor opened with the first-team offense Monday, lining up at the "X" as Alshon Jeffery is on the Physically Unable to Perform list and J.J. Arcega-Whiteside is "day-to-day" with a lower-body injury. The Eagles' rookie looked in sync immediately with starting quarterback Carson Wentz, a strong sign of things to come for the new-look offense.

"It's been a lot of fun to work with Jalen. He is an explosive athlete," Wentz said on a conference call after Eagles' practice Monday. "You can see that with his route-running ability and his down-the-field presence. You turn on his highlight tape and you see what he does with the ball in his hands -- and that's one thing we haven't been able to see, obviously, with just practice going on and nothing live."

Reagor could jump right into action as a starter as Jeffery may remain on PUP to start the season, according to some reports. Reagor ran smooth routes and showed a lot of explosiveness, according to the rest of the story. Given the Eagles struggles at WR last season, having Reagor ready for action will be a big boost to the offense.
