NEW YORK — A person with knowledge of the situation told The Associated Press that quarterback Tim Tebow, acquired from Denver on Wednesday, must sign a rewritten contract because of a technicality before he can officially join the Jets.

That issue keeps Tebow on Denver's salary cap for 24 hours after he signs the new deal, according to the person who spoke on condition of anonymity because the reason for the delay hadn't been announced by the Jets.

ESPN first reported the contract issue.

Tebow arrived at the team's facility in Florham Park, N.J., but the Jets won't officially introduce him until Monday because of the delay.
