Saunders missed the last two preseason games after suffering the seizure en route to the Jets' facility before the Bengals game.
The wide receiver was a full participant in practice on Monday.
Florham Park, N.J., police released an accident report which said Saunders had a “medical event” while driving a 2014 Toyota Corolla. Saunders, driving to the Jets facility to begin the trip to Cincinnati, was attempting to make a left turn from southbound Park Avenue onto Florham Road about 7:50 a.m. He failed to make a full turn, crossed the northbound lanes and struck a curb before coming to rest in the grass, less than a mile from the facility.
