Broncos defensive end Derek Wolfe was released from a Denver hospital Monday after suffering seizure-like symptoms when the team's bus pulled into the airport Friday afternoon for the flight to Kansas City.
Wolfe was treated by the team's medical staff and then transported by ambulance from the airport to the hospital.
It was determined that Wolfe didn't suffer a stroke or a full-blown seizure, but the Broncos didn't specify the exact cause of his symptoms, saying Saturday evening that he was doing better and that he was alert and communicating with others
Wolfe isn't expected to be out long.
"They're still running tests," Broncos coach John Fox said Monday. "I think they're still trying to get a handle on what happened and compare it. I'm not saying it's nearly the same, but some of the same things we went through with Tracy Porter a year ago.
"Right now we're not thinking about his availability or any of that stuff. We're just concerned about his health, and medical people are working through that as we speak."
Wolfe went through Friday's practice without incident and had not been on the team's injury report through the week, but he has had a difficult year. He was taken from the field by ambulance during a preseason game in Seattle when he suffered a head and neck injury on a tackle. Wolfe experienced numbness in his limbs immediately following the play, but did return to Denver with the team following the game.
Wolfe was held out of practice for several days. He then had a bout with food poisoning in September and coaches said at that point he was having at least some difficulty keeping his weight up.
