GAINESVILLE, Fla. -- No. 23 Florida likely will be without quarterback Luke Del Rio against Southeastern Conference rival and 15th-ranked Tennessee next week.Del Rio injured his left knee in a 32-0 victory against North Texas on Saturday night, a huge setback for the Gators and their championship hopes.It doesnt look great, so well do whatever, said coach Jim McElwain, adding that former Purdue starter Austin Appleby would be the next guy up. Somebody else will play and well get some guys ready and move forward and get ready to go play next week.The injury overshadowed a dominant performance by Floridas defense, which allowed a school-record 53 yards on 50 plays. The previous mark was 59 yards allowed against Western Carolina in 2006.Defensive lineman Joshua Wheeler hit Del Rio low at the end of incomplete pass late in the third quarter, drawing a personal-foul penalty. Trainers and coach Jim McElwain rushed to the field as Del Rio ripped off his helmet. Del Rio eventually got up and walked to the locker room without any assistance.But that was hardly the end of it for Florida (3-0). McElwain, who initially believed Wheelers hit was dirty, started yelling at the North Texas (1-2) sideline and had to be restrained by officials and then his players.I obviously took that low hit on Luke awful personal, McElwain said. Im sure his guy was just scrambling trying to make a play, but I really care about these players. I care about them in more ways than just football players, and when you see something like that, its my responsibility when their parents arent here to be their parents.Both teams responded to McElwains tirade by stepping onto the field and moving toward the hash marks.I care about these kids, McElwain said. Theyre mine. I see something like that, it aint right.On the next play, Florida guard Martez Ivey was ejected for grabbing linebacker Fred Scott by the facemask during a run. Ivey will not be suspended for the first half of next weeks game against the Volunteers.Del Rio completed 14 of 25 passes for 186 yards, with an interception.THE TAKEAWAYNORTH TEXAS: Coach Seth Littrell, a former offensive assistant at Arizona, Indiana and North Carolina, is trying to change the culture at North Texas. Playing the Gators tough early -- the score was 19-0 through three quarters -- was a good start and something to build on in Littrells first season.FLORIDA: The tune-up games are over. While handling UMass, Kentucky and North Texas, Floridas defense was dominant and its offense remains a work in progress -- especially without Del Rio. It remains to be seen how the Gators young and inexperienced offensive line will fare against the meat of the schedule.POLL IMPLICATIONSFlorida should remain at or near No. 23 , making next weeks game at Tennessee the second in eight years in which both rivals were ranked. They also were both ranked in 2012. The Gators, who have won 11 in a row in the series, and Volunteers were both unranked the previous two meetings.UP NEXTNORTH TEXAS: Opens Conference USA play at Rice (0-3). The Mean Green are 2-4 all-time against the Owls.FLORIDA: Plays the Volunteers (3-0) for the 27th consecutive year. Florida is 20-6 during that stretch, including 11 straight wins that mark the longest streak since the programs first played in 1916.---AP college football website: www.collegefootball.ap.org Wholesale Jerseys .
