"That's not the first or last time you're going to see emotional players on the sideline," Shurmur said. "What's important is that there's developed relationships with everybody and there's not a problem as we move forward."
Bicknell is the second position coach in Jackson's NFL career. Jackson spent his previous five seasons working with David Culley.
"Still an open relationship," Jackson said. "Still getting to know each other. Still early on. It's been a couple of months since we've been here together."
Jackson is having his finest season with the Eagles. He has 75 catches for 1,275 yards and nine touchdowns. He is 135 yards away from breaking Mike Quick's single-season record after a 10-catch, 195-yard performance against the Vikings.
"If I reach it, it's a blessing, it's a great achievement," Jackson said. "Regardless of my stats on Sunday, we lost the game. So it probably would have meant a little more, been a lot better if we could have won."
The Eagles signed safety Keelan Johnson from the practice squad and released Emmanuel Acho. Johnson, who is 5-foot-11 and 212 pounds, has spent the season with the Eagles after playing for the Miami Dolphins during training camp and the preseason.
Linebacker Najee Goode practiced Tuesday after missing two games, which explains why Acho was expendable. Acho had been inactive when all the linebackers were healthy.
The back of Nick Foles' right hand was covered by a scab when he met reporters after practice, but Foles was unconcerned.
"Just a little scab," the quarterback said. "Football, you get hit."
