LINCOLN, Neb. -- Less than an hour after he was loaded into an ambulance after getting knocked unconscious against Ohio State, Nebraska quarterback Tommy Armstrong Jr. was back on the sideline with teammates.His rapid return was encouraging to anyone who saw Armstrong lay motionless following a hit by Malik Hooker on Saturday night. It also was a bit surprising.Dr. Robert Cantu, a concussion expert and co-founder of a center that studies head trauma at Boston University Medical School, on Tuesday told The Associated Press a raucous football sideline typically wouldnt be the ideal environment for a person who just sustained a concussion.We normally dont encourage people to be in stimulating circumstances right after a concussion, Cantu said. So we normally wouldnt bring someone back to the sideline. Wed keep him in a quiet environment -- not a dark room and all that, but not the stimulation of a football field. So thats a bit atypical.But I dont know what his symptomatic status was, Cantu added. If everything cleared up real quickly, it wasnt necessarily wrong.Armstrong, according to Nebraska director of athletic medicine Dr. Lonnie Albers, went through a very thorough medical and imaging process at the Ohio State Wexner Medical Center and left the hospital without symptoms.A member of the Nebraska medical staff was present throughout the evaluation at the hospital, through the dismissal process, and on the sideline upon Tommys return to the stadium, Albers said in a statement. Tommy left the hospital symptom-free and reported no symptoms during post-dismissal monitoring at the stadium.Coach Mike Riley said Monday that Armstrong was going through a concussion protocol and would require clearance from the athletic departments medical staff in order to play in this Saturdays game against Minnesota. Riley characterized Armstrong as day to day.Cantu, a consultant to the NFL Head, Neck and Spine Committee, said if Armstrongs symptoms cleared up quickly, it would not be unreasonable to expect him to be ready to play in the next game.The important thing is how fast the symptoms cleared up, Cantu said. The fact he was briefly unconscious is largely not important in terms of severity of the concussion. The severity of the concussion is much more correlated to how long it takes for symptoms to clear. So the fact he was unconscious for a few seconds, that means he had a concussion and needs to be checked out, but it doesnt necessarily mean its going to be a long period of time hes away.Nebraskas concussion protocol will require Armstrong to complete a computerized neurocognitive test to show he has returned to his normal neurological state. He then will be monitored to see how he tolerates increasing levels of activity. If he shows he can handle activity without worsening or new symptoms, hes allowed to return to competition.Dr. Arthur Maerlender, director of clinical research at the universitys Center for Brain, Biology and Behavior, is charged with interpreting Armstrongs neuropsychological test results in the protocol.There is no magic window of time to stay out, Maerlender wrote in an email to the AP. Loss of consciousness (LOC) is not a very good predictor of anything. Given current knowledge, athletes can return to contact if all signs, symptoms and test scores are back to baseline and they complete a step-wise physical exertion process.Future research may show that to be inadequate, but we have no solid evidence of that yet, he said.---More AP college football at http://collegefootball.ap.orgRoy White Jersey .

Track and field was also hit, with Greek triple jumper Chrysopigi Devetzi and Ukrainian pole vaulter Denys Yurchenko losing their bronze medals. Yurchenkos ban could elevate Derek Miles of the United States to the bronze-medal position.Six athletes who did not win medals in 2008 were also disqualified.There could be another U.S. medal for high jumper Chaunte Lowe, who originally finished sixth but is now in line to inherit bronze.Among those disqualified Thursday were the athletes who had finished in the two places immediately above Lowe, Russias Elena Slesarenko and Ukraines Vita Palamar. The bronze-medal position was vacated laast month when the IOC said Russian Anna Chicherova had tested positive for the steroid turinabol.ddddddddddddThe IOC ruling also casts a shadow over the career of Slesarenko, who was the gold medalist in 2004, though she will not be stripped of that title under Thursdays ruling.The three silver medalists affected are Azerbaijani wrestler Vitaly Rahimov, Russian wrestler Khasan Baroev and Kazakhstan weightlifter Irina Nekrasova. Weightlifting has been by far the worst-hit sport in retests and saw nine more athletes sanctioned Thursday, taking the sports total for the 2008 Olympics alone to 22.Other athletes who stand to benefit include Canadian weightlifter Christine Girard, who could move up to the bronze position because of Nekrasovas disqualification, and Mariam Usman, who would become only the second Nigerian to win a weightlifting medal with bronze after Kazakhstans Maria Grabovetskaya was disqualified from third.
