Tulane football player Devon Walker's fractured spine was stabilized in a three-hour surgery Sunday, though it's too soon to tell whether he will be paralyzed from the injury he suffered while making a tackle, the team's doctor said.
Dr. Greg Stewart, Tulane University's director of sports medicine, said Walker was in stable condition and was expected to stay in the intensive care until of St. Francis Hospital in Tulsa, Okla., for the next few days.
"These kind of injuries take 24, 48, sometimes 72 hours to fully declare themselves," Stewart said before the surgery. "We don't know what the long-term implications and outcomes are going to be."
Stewart said he was with Walker on the field, in the ambulance and at the hospital Saturday after Walker and defensive tackle Julius Warmsley collided head-on while making a tackle on the final play of the first half against Tulsa.
Stewart said Walker was put into a cervical collar and couldn't see much of what was happening, so Stewart explained what was going on. Walker was talking with doctors as he was being treated, Stewart said.
Walker's parents had traveled to Oklahoma to be with their son, and they were "doing as well as can be expected," Stewart said.
"They're like the rest of us -- hopeful and prayerful."
Stewart was back in New Orleans on Sunday, as were Walker's teammates. He said Tulane's athletic director and the football team's trainer remained in Oklahoma with
AP Top 25: Arkansas has taken the second-largest fall out of the AP college football poll, dropping from eighth to unranked after losing to Louisiana-Monroe.
The Razorbacks were upset 34-31 in overtime after losing quarterback Tyler Wilson to an injury. The only team to take a more drastic fall from the poll was Michigan in 2007. The Wolverines opened the season at No. 5 and dropped out after a Week 1 loss to Appalachian State.
Alabama remains No. 1. USC is No. 2, followed by LSU and Oregon. Florida State moved into a tie for fifth with Oklahoma. Georgia is No. 7.
Stanford moved up four spots to No. 21.
Arkansas was one of four teams to drop out, along with Nebraska, Wisconsin and Oklahoma State. Moving in were UCLA, Tennessee, Arizona and BYU.
Arkansas: Coach John L. Smith says quarterback Tyler Wilson's prognosis is good heading into this week's game with Alabama. Wilson missed the second half of Saturday's loss to Louisiana-Monroe after taking a hit to the head and stayed in Little Rock overnight.
Wilson also missed the second half of a game last season with concussion-like symptoms.
The Razorbacks, meanwhile, are getting an early test on how they'll handle the difficult times without former coach Bobby Petrino. They blew a 21-point second-half lead in the shocking 34-31 overtime loss to Louisiana-Monroe.
Without Petrino, who was fired in April after his well-publicized off-the-field transgressions, Arkansas' defense was embarrassed and outmatched by Warhawks quarterback Kolton Browning, who accounted for 481 yards of total offense and four touchdowns.
"I am shocked, and I am mad at the same time," Arkansas middle linebacker Tenarius Wright said. "I don't want to show anger. I want to be strong for my team, and our team has to come together and stay together as a family and get ready for next week."
Notre Dame: Coach Brian Kelly said starting quarterback Everett Golson's thumb injury was not the deciding factor when he was pulled in favor of Tommy Rees. Kelly made the choice because of Rees' knowledge of the two-minute offense. Rees led the Irish into position for a game-winning field goal Saturday and a 20-17 win over Purdue.
Using a baseball analogy, Kelly said his preference is for his starter to pitch a complete game but added sometimes it's necessary to bring in a reliever. Kelly said Golson is fine and will be back as the starter this Saturday when the Irish (2-0) face Michigan State.
North Dakota State: A school official says football players who have been charged with faking petition signatures to get measures on the November ballot will not be suspended from the team. Officials said previously that any discipline would want until after misdemeanor fraud charges were resolved.
Nine players are among 15 people accused of faking signatures on well-funded initiatives dealing with a conservation fund and medical marijuana.
With the suspect petitions disqualified, neither initiative had enough signatures to get on the ballot.
