Vick was hurt in the third quarter of Sunday's game at Atlanta, which the Falcons won 35-31. The quarterback was hit by Falcons safety William Moore and his helmet struck a teammate.
He was helped off the field and didn't return to the game.
"He's resting right now, but last night he was pretty good," Eagles head trainer Rick Burkholder said of Vick Monday. "He told coach he was fine. He told his teammates he was fine."
Burkholder said tests on Vick in the locker room in Atlanta indicated a concussion although the injury wasn't seen as severe.
"We have a baseline of tests and he was a little bit off," Burkholder said. "He was close [to being able to return]. We had to make a medical decision ... and we made the right decision."
The trainer said Vick would go through normal protocols this week to determine if he would be available Sunday when the Eagles have their home opener versus the New York Giants.
Burkholder, however, wouldn't commit to a timetable for Vick's possible return.
Third-string quarterback Mike Kafka replaced Vick Sunday as usual second-team quarterback Vince Young is recovering from a hamstring injury.
