Severity of Hawaii QB's injury unknown

Posted by ESPN.com’s Graham Watson

Hawaii is waiting to learn the extent of a knee injury suffered by quarterback Greg Alexander during the 27-6 loss at Louisiana Tech.

Alexander was scrambling during the third quarter when he took a shot from Louisiana Tech linebacker Adrien Cole and remained on the Hawaii sideline.

Alexander was eventually carted off the field.

"I just heard a pop, I don't know what happened," Alexander told the Honolulu Star-Bulletin. "It happened pretty fast, I think it got stuck in the turf a little bit, I'm not really sure."

Alexander was originally diagnosed with a sprained left knee, but is scheduled for an MRI on Sunday, according to the Star-Bulletin. He left the stadium Wednesday night on crutches and with a large brace wrapped around his leg.

"We don't know the extent of the injury, but it's not good," coach Greg McMackin said after the game.

Alexander came into Hawaii’s WAC opener as the nation’s leader in total offense, averaging 446 yards per game. He ranked second in passing average and fifth in passing efficiency. But Alexander struggled to get anything going against a stingy Louisiana Tech defense that kept pressure on him in the backfield all night. The Bulldogs sacked Alexander five times and sacked backup quarterback Bryant Moniz twice.

The Warriors were held without a touchdown for the first time since 2004, ending a streak of 62 games.

Alexander had passed for 199 yards and two interceptions at the time of his injury.
