Sophomore offensive tackle Bobby Williams was taken from the practice field in an ambulance after being hit in the head in a scrimmage near the end of Tuesday's practice.
Williams was taken to Shands at the University of Florida. He was hospitalized overnight.
Tests on his head and neck came back normal.
Coach Ron Zook said Williams was coherent and had feeling and movement in his arms and legs.
Though Williams lay on the field for several minutes, Zook said team doctors did not think he ever was unconscious.
Zook said Williams was wearing the new helmet with added padding that is supposed to help prevent concussions.
"There are a lot of collisions in college that would cost NFL guys thousands of dollars," Zook said. "There were a couple shots in that game last week that would cost them thousands of dollars in the NFL. That's one thing they don't mess around."
He did not know what or with whom Williams collided, but he called the play a cut block.
"I'm not sure if he got hit in the head with a knee or hit the ground," Zook said. "It was a zone play and I'm not sure if there was anybody who specifically hit him."

Leg may sideline Sam
TALLAHASSEE _ The Seminoles might have to be without wideout P.K. Sam for Saturday's game against N.C. State.
Sam, who missed two games this season with a hamstring pull, reinjured his leg.
"P.K. is probably questionable," coach Bobby Bowden said. "He pulled a leg muscle; if you go too fast it pops, so we are trying to not let him. We'll have to see how he's doing."
Sam has 13 receptions for 162 yards.
Dominic Robinson and Robert Morgan would replace Sam in three- and four-receiver sets.
MADDOX IMPROVING: Bowden was encouraged by running back Nick Maddox's practice, though the senior did not take part in contact drills.
"It would take an accident this week in practice to keep him out," Bowden said.
Maddox sprained his ankle against Georgia Tech and missed Saturday's game against North Carolina. Bowden said Maddox could have played, but he held him out as a precaution.

Bulls face big challenge
TAMPA _ South Florida practiced for more than two hours, and coach Jim Leavitt said his biggest concern for Saturday's game is Houston's jumbo-sized offensive line and Conference USA's leading rusher, Joffrey Reynolds (1,337 yards).
The Cougars left tackle (Chris Redding) and left guard (Roy Swan) average 355 pounds, and all five starters are more than 300.
"These guys are massive," Leavitt said. "They lock on you and they just feed him the ball."
THE BEST: Quarterback Marquel Blackwell leads the nation with a 0.82 interception ratio (three in 367 attempts), ahead of Notre Dame's Carlyle Holiday (1.02, two in 197 attempts). Blackwell has a national-best 199 straight attempts without a pick, since Oct. 5 at North Texas.
With bowl games counting toward individual season statistics for the first time, Blackwell could have two more games to try to surpass Trent Dilfer's record 271 passes without an interception, set in 1993 at Fresno State.
TACKLING FOOLS: Linebacker Kawika Mitchell was credited with an extra tackle Saturday, giving him 107, a USF record surpassing his 106 last season. Mitchell and Greg Walls are tied with a school-record 17 tackles for loss.
NO. 1: USF's nine penalties against Bowling Green allowed it to maintain the national lead with 118. Louisville is next with 109.
