SYRACUSE - All of a sudden, Syracuse head coach Greg Robinson is staring at the final three games of his third season with the Orange not knowing who his starting quarterback will be.

Andrew Robinson, who has started every game this season, is day-to-day after an MRI revealed he has a slight crack in a rib on his upper left side. He started in Saturday's 20-17 loss at Pitt but was replaced by Cameron Dantley in the second half.

“It's really a matter of him just working and seeing where we are,” Greg Robinson said Tuesday. “We don't know when he got the injury. He was hurt last week and didn't practice Wednesday, Thursday and Friday. At one time, he thought it was a muscle. When you have a little injury like that, your muscles really work to shield the area.

“We were just trying to rest him and trying to get him to where he was, hopefully, feeling better, and I think he felt like he was feeling better,” Greg Robinson said. “He was still real tight. That was really how the week was, which in some cases was really good because it gave Cam (Dantley) a good amount of work.”

Greg Robinson said he would have to wait to see what Andrew Robinson feels comfortable with as the week progresses before deciding if he'll start Saturday at home against Big East foe South Florida (6-3, 1-3 Big East).

“Andrew's not going to play if we think he's in jeopardy,” Greg Robinson said. “If he's playing, it's because he can go.”

In the first extended stint of his career, Dantley, a former walk-on and the son of former NBA star Adrian Dantley, acquitted himself well, Although the Orange (2-7, 1-3) never found any consistency on offense, Dantley threw two touchdown passes, hitting Taj Smith on a 56-yard toss down the middle on Syracuse's second possession after halftime to tie the game at 10.

Dantley also threw a 3-yard TD pass to Mike Williams with 1:46 remaining in the game and ended 15-of-27 for 189 yards after previously attempting only four passes all season.

Andrew Robinson said he was feeling a lot better than he was after Saturday's game but cautioned it was too early to say if he would play this week.

“We're really going to take it as a day-by-day thing right now, see how I feel,” Robinson, who has been the victim of most of the 37 sacks allowed by Syracuse's beleaguered offensive line, said Tuesday. “It's my first rib. I thought I had a back injury of some kind. To be honest, I can't really tell you when I cracked it. We were thinking it might have been a hit I took in the Buffalo game or the game before that, and I possibly aggravated it in the weight room.”

For the season, Robinson is 117-for-224 passing for 1,714 yards, 10 touchdowns and six interceptions. And he's not looking forward to the prospect of watching a game from the sideline.

“I've never missed a game or practice in my entire life. It's a little bit foreign to me,” he said. “I was excited the way Cam played, he put the team in position to win. But at the same time, me being a competitor, I want to be out there playing.”

Greg Robinson hinted that quarterback-turned-safety Joe Fields might get some work at his old position in practice this week just in case. The senior, who leads the team with 72 tackles and three interceptions, smiled at the thought.

“I'll do whatever I can to help the team,” Fields said. “You really can't so no if coach says you can help the team this way. But I don't see that happening.”

Notes: Mike Williams had a career-high eight catches against Pitt for 81 yards and set a school record with a touchdown reception in his sixth straight game to bring his season total to seven.
