"We have had calls," the team official said Wednesday.
When asked Wednesday whether Kolb would be on the Eagles' roster after the Oct. 19 trade deadline, Eagles coach Andy Reid said, "Listen, I can't predict anything down that far; nobody in this league can do that."
Kolb has missed the past six quarters because of a concussion, and Michael Vick played well in his absence. Kolb was cleared to practice and was expected to run the first-team offense Wednesday.
However, Tuesday night, Vick was named the Eagles' starting quarterback, with Reid saying, "When someone is playing at the level Michael Vick is playing, you have to give him an opportunity."
Vick came on in relief of Kolb after Kolb suffered a concussion in a 27-20 season-opening loss to Green Bay.
Vick threw for 175 yards and one touchdown and ran for 103 yards, and this past Sunday he passed for 284 yards and two touchdowns in the Eagles' victory over the Detroit Lions.
