The sideline spat between offensive coordinator Marty Mornhinweg and defensive line coach Jim Washburn was set off by a bump on the sidelines, according to an Eagles source.

Mornhinweg bumped into Washburn at one point Sunday night, and the fiery defensive line coach took exception. Mornhinweg wouldn't back down, and the two had to be separated by team personnel, the source said.

Play-calling was not at the root of the incident.

Mornhinweg has not talked to reporters since the game, though, so players were left to answer questions about the dustup.

"That's a tough situation because that should never happen," said running back LeSean McCoy. Discussing the fracas between the 49-year-old Mornhinweg and 61-year-old Washburn, McCoy, 23, said, "coaches or players, we're in this thing together. I guess things happen playing a sport like this. Everything's always a team, team first. You might have disagreements, guys might feel a certain type of way, but you work it out."

Other players attributed the problem to the heat of a tough game.

"In the course of a game, there's always bullets flying," said wide receiver Riley Cooper. "Sometimes coaches argue, sometimes players argue. Brothers and sisters argue. You really don't look too much into it."

Tight end Brent Celek said that issues are magnified in harder times.

"When you're losing games, people get heated, and there's times when you have words with each other but you get over it," Celek said. "It's just when you're losing that it gets put on a bigger stage."

Or it could be a sign of more serious fracturing.

Jackson still starting. DeSean Jackson was working with the first-team offense during Monday's walk-through, according to one Eagles player, despite the star receiver being benched late in Sunday's loss.

Jackson said he didn't get an explanation for why he was sidelined and didn't want one. He was asked if he still wants to play in Philadelphia.

"Yes sir," Jackson said. "That's where I'm at, and that's what I love to do, play football."

McCoy backs Reid. McCoy joined coach Andy Reid in saying he didn't hear the "Fire Andy" chants at Lincoln Financial Field Sunday, and backed his coach.

"If guys are missing blocks or not hitting holes, things like that, missed coverages, whatever it is, fumbles, why should Andy Reid have to suffer for that? It's not his fault," McCoy said.

"I've never seen a coach catch a pass, throw a ball, make a tackle," added Celek. "It just comes down to us executing it."

Graham: I'm ready to play. Defensive end Brandon Graham, inactive the last two weeks, said he is healthy enough to play. He chalked his spot on the sideline up to coaches' decisions.

"I know what I can do, and I'm going to stay ready," said Graham, last year's first-round pick. He noted that with Juqua Parker back, the Eagles are fully healthy at defensive end. "They feel like I guess they don't need me until something happens."

Injury Update. McCoy (toe) was a surprise addition to the injury report. He was listed as limited in the Eagles' light walk-through Monday, though he didn't miss any time Sunday. Defensive tackle Cullen Jenkins was also limited after getting stitches in his thumb Sunday. He said he would be fine to play Thursday night.
