Florida's Tebow sent home with concussion

Florida quarterback Tim Tebow was out of the hospital and back home yesterday, recovering from the concussion he suffered during the Gators' 41-7 victory at Kentucky.

Tebow was released in the morning from the University Medical Center in Lexington, Ky. He had been held for precautionary reasons. Coach Urban Meyer spent the night in the hospital with Tebow.

"Tim is doing fine this morning," Meyer said. "His CT scans came back and indicated that Tim suffered a concussion. Our medical and athletic training staff will continue to monitor him to determine how much rest and recovery he needs. We will have additional information and updates this week."

Tebow flew back to Gainesville, Fla., with his family and Meyer yesterday afternoon.

The top-ranked Gators (4-0) are off this week, then will play at Louisiana State on Oct. 10. It might be several days, maybe longer, before Tebow's status becomes clearer for that game.

The Gators were leading by 31-7 in the third quarter and driving deep in Kentucky territory when defensive end Taylor Wyndham came unblocked off the right end and sacked Tebow. As Tebow fell backward, his helmet struck teammate Marcus Gilbert's leg, violently bending his neck forward.

QB out for season. Baylor quarterback Robert Griffin will miss the rest of the season with a right-knee injury. An MRI exam revealed that Griffin has "an isolated tear" in his anterior cruciate ligament, the Bears said. He was hurt Saturday night during Baylor's 68-13 victory over Northwestern State.

The polls. After a weekend in which four top-10 teams lost, the Associated Press college football poll received a major makeover.

No. 1 Florida, No. 2 Texas, and No. 3 Alabama held their places, but 15 teams moved up or down at least three spots.

LSU is up to No. 4 after barely avoiding an upset at Mississippi State on Saturday. No. 5 Boise State is in the top five for the first time in the regular season.

After its loss to Iowa, Penn State went from fifth to No. 15.

No. 6 Virginia Tech, No. 7 Southern California, and No. 9 Ohio State are back in the top 10.

Cincinnati moved up four spots to No. 10, the best ranking in school history.
