Jackson, who has not granted extended interviews since his arrival at camp two weeks ago, declined to comment. Maclin would not divulge what led to the spat, but it occurred after a seven-on-seven drill.
When practice ended, the two receivers walked the length of one field with Maclin often gesturing with his hands and Jackson listening. As they got closer to a gaggle of reporters, Maclin could be heard saying, "We're still cool." They then proceeded to the autograph line, where each signed for a number of fans.
"It was nothing major," Maclin said. "Like I said, it was over and done with."
Maclin and Jackson stood near each other during the afternoon practice without incident, but the argument brings into question the relationship that exists between two hard-working, ambitious receivers.
There are only so many passes to go around - even in the Eagles' pass-heavy offense - when you factor in the starting wide receivers, a sure-handed third receiver in Jason Avant, a Pro Bowl-caliber tight end in Brent Celek, and pass-catching running backs led by LeSean McCoy.
Eagles coach Andy Reid, offensive coordinator Marty Mornhinweg, and quarterback Kevin Kolb will be charged with keeping all those egos content.
"I think everybody wants to be a star and wants to have the ball in their hands," Kolb said. "But we just have to keep pressing the fact, 'Look, we're a good offense. Everybody's going to get their shot. Everybody's going to get their plays.' "
Jackson, in just two seasons, has arguably become the league's most dangerous big-play threat. Maclin, the Eagles' top pick last year, is an emerging talent after a solid rookie season. One of the two will likely have to see fewer opportunities.
