IRVING, Texas, Oct. 28 (UPI) -- Seattle Seahawks wide receiver Darrell Jackson Sunday suffered a seizure in the team's locker room after sustaining a concussion in the game against the Dallas Cowboys.
Jackson was taken by ambulance to Baylor Medical Center, where he was listed in stable condition and was to remain at least overnight.
Seahawks team physician Dr. Ed Khalfayan said the seizure likely was caused by a lack of oxygen to the brain, but said that Jackson never lost consciousness.
"He kept breathing the whole time, recovered from the seizure and was a bit confused afterwards," Dr. Khalfayan said. "He was not receptive to any information and had movements in his extremities, which are very typical of a seizure."
Jackson, 23, took a brutal hit, high and hard, from Cowboys safety Darren Woodson while attempting to catch a pass over the middle with 5:20 left in the fourth quarter. Woodson was flagged 15 yards for an unnecessary roughness penalty on the hit.
On the play, Jackson sustained a concussion, but was able to walk off the field. After the game, he was sitting in the training room talking to fellow wide receiver Bobby Engram when the seizure occurred.
"They were sitting there, then all of a sudden, he went out," said Seattle Coach Mike Holmgren. He recognized me, he recognized people. We had a heck of a time getting him to lay still, so we could load him into the ambulance."
Jackson was not receptive to any of the information that was asked of him before slipping into the seizure.
"Seizures are caused by a number of different reasons, most likely due to a lack of oxygen to the brain," explained Khalfayan.
Engram and wideout Koren Robinson went to the hospital to be with Jackson, a third-round pick in 2000 out of Florida, who leads the Seahawks with 30 receptions for 377 yards. He had 123 catches for 1,794 yards and 14 touchdowns in his first two NFL seasons.
