Tebow, known for his early arrivals, checked in about 90 minutes before the start of an 8 a.m. team meeting. How long he remains with the Jets has been an ongoing question throughout the offseason. The team is prepared to part ways with the quarterback and they've been trying to trade him.
Star cornerback Darrelle Revis, the subject of intense trade speculation, is expected to participate on the first day, but he will arrive late. His first order of business Monday was an appointment in Manhattan with Dr. Russell Warren, who performed his knee surgery last October.
After a check-up and MRI, Revis will join his teammates at the Jets' facility in Florham Park, N.J.
Revis wanted to remain in Arizona, where he has been rehabbing his knee since January, but he reported because the team refused to excuse him for two weeks, sources said. The Jets' decision didn't sit well with Revis, touching off a dispute between the two sides.
He preferred Arizona, in part, to avoid the distraction of being with the team during trade talks with the Tampa Bay Buccaneers. There's a chance he could be dealt before the April 25 draft.
Revis also has a $1 million workout bonus that he would forfeit if he doesn't participate in 83 percent of the voluntary workouts.
Tebow has no financial incentive, but he declared over the weekend at his charity golf tournament in Ponte Vedra Beach, Fla., that he'd show up for the voluntary program with "a great attitude." He also said the offseason has "been my best yet."
The media has no locker room access Monday, minimizing the attention, but a few players will speak later to reporters via conference call.
