INDIANAPOLIS, DEC. 22 -- The Washington Redskins had a few scary moments tonight when cornerback Sidney Johnson was knocked unconscious while covering a first-quarter kickoff during a 35-28 loss to the Indianapolis Colts at the Hoosier Dome.

Johnson lay motionless on the artificial turf for 20 minutes and was still unconscious when he was lifted onto a stretcher and wheeled off the field.

He regained consciousness while being taken to Methodist Hospital, where he will remain one or two nights and undergo more tests.

"Sidney is going to be fine," said Redskins internist Donald M. Knowlan accompanied Johnson to the hospital. "He woke up in the ambulance and tested normally. He'll stay a night or two. It's up to them. But he's going to be okay."

Johnson was examined by a neurosurgeon, another doctor and an orthopedist while still down on the turf and was to undergo a CAT scan Sunday morning. Team doctors said they found no abnormalities at the hospital and that the only lingering problem should be a severe headache for a few days.

Replays were inconclusive about how Johnson was injured. It appeared that he collided with a Colt, who buried a helmet into his chest and throat.

Teammates huddled around him as doctors and trainers attended to him on the field, and television cameras caught Redskins defensive end Jumpy Geathers bending down saying a prayer.

Johnson was signed by the Redskins Oct. 17 after Johnny Thomas was placed on waivers. He was a late training camp cut by the Kansas City Chiefs.
