IRVING, Texas -- Seattle Seahawks receiver Darrell Jackson sustained a concussion late in Sunday's game against Dallas, then had a seizure in the locker room and was taken to the hospital.

Seahawks coach Mike Holmgren said Jackson was in stable condition. The receiver was transferred to Baylor Medical Center, where he was expected to stay at least overnight.

A CT scan taken Sunday night was clear, but Jackson was scheduled to undergo another one on Monday.

A source close to the wide receiver told ESPN.com on Sunday night Jackson was conscious and was doing well. It was still unknown, however, when he might be able to return to Seattle.

Jackson never returned after taking a hard, high hit from Cowboys safety Darren Woodson with 5:20 left in the Seahawks' 17-14 win. Woodson was penalized for unnecessary roughness.

After the hit, Jackson stayed on the sideline and walked off the field with his teammates after the game. He was sitting in the training room, being observed by team physician Ed Khalfayan and talking to receiver Bobby Engram when the seizure occurred.

"They were sitting there, then all of a sudden, he went out,'' Holmgren said.

Khalfayan said the seizure likely was caused by a lack of oxygen to the brain, and added that Jackson never lost consciousness.

"He kept breathing the whole time and recovered from the seizure and was a bit confused afterwards,'' Khalfayan said. "He was not receptive to any information and had movements in his extremities.''

The locker room was cleared of non-team personnel right after the seizure occurred, and it took about 45 minutes before Jackson was put into an ambulance.

Holmgren said much of that time was spent trying to calm Jackson.

"You become combative. You're disoriented a little bit and become combative,'' Holmgren said. "You recognize things and recognize people, but they had a heck of a time getting him to lay down so they could put him in the ambulance.''

Jackson recognized Holmgren and other people caring for him, the coach said.

Receivers Koren Robinson and Engram went to the hospital to be with Jackson. Holmgren called his family.

"They were watching the game and knew he got hit,'' Holmgren said.

Jackson was injured on the second play of a 13-play drive that resulted in Rian Lindell's game-winning 20-yard field goal with 20 seconds left.
