UPDATE, 11:46 a.m.: Byron Storer revealed he has a torn ACL and will miss the rest of the season. More on the subject later.

"It's bad news," he said.

"I was just trying to play over the top of a guy and the leg gave out. It wasn't a hit or anything. It was the funniest thing. . . I had never had problems with knees or anything. I've never really had a major injury."

Now we know what Gruden meant when he said this morning, "We're in trouble right now at fullback."

The Bucs could make a trade or sign a free agent to fill in, or they could choose to play B.J. Askew, who is nearing his return.

POSTED, 11:23 a.m.: Bucs coach Jon Gruden just completed his Monday news conference and revealed great concern about the fullback position, where the Bucs lost their lone healthy player on Sunday.

Backup Byron Storer sustained a knee injury and is expected to have an MRI exam performed today in an effort to determine the extent of the damage. His injury is compounded by B.J. Askew's hamstring injury, one that has sidelined him for three weeks and could keep him out longer.

The Bucs may be forced to make a roster move to address the situation, Gruden said.

"We're going to have to do something," Gruden said. "We're a two-back team."

There's also concern about injuries to WR Maurice Stovall (hamstring) and LG Arron Sears (knee). They, too, are being evaluated today.
