Saunders was involved in a one-car accident and was hospitalized for two days. He wasn't injured, but he underwent neurological testing. He experienced a "medical event" moments before the accident, according to the police report. The Jets didn't confirm the diagnosis until Monday.
"He had a seizure, and that's the extent of what we know," coach Rex Ryan said. "We let the professionals handle it. When the doctors were confident that he would be cleared, he was -- and that's where he's at now."
Ryan didn't give any specifics on the cause of the seizure, although he has indicated there was no pre-existing condition.
Saunders, a fourth-round pick from Oklahoma, practiced Sunday in a red, no-contact jersey. On Monday, he was a full participant. He's expected to play in the final preseason game, Thursday night against the Philadelphia Eagles.
Asked about the seizure, Saunders said, "That's what happened, I guess. I'm not going to try to relive that moment again. ... I feel 100 percent and I'm glad I'm back on the field. I'm blessed to be alive."
The Jets expect Saunders, only 5-foot-9, 170 pounds, to emerge as their primary punt returner.
"I'm sure everybody is excited to see him," Ryan said. "I'm sure all of the Jets fans are excited. I know that I'm excited to see him play. For somebody to go through something like that, and now to get back to where he's cleared to play football, I think that's really big for him."
