Collaros was hit hard on a scramble late in a 38-30 loss to South Florida on Friday night. He stayed in the game for one more play -- a touchdown pass -- then was held out for the Bearcats' final series as a precaution. He had medical tests over the weekend.
Coach Butch Jones said Collaros will be allowed to practice on Tuesday, when the staff will get a better idea of what he can do.
"We'll know a little more as the week progresses," Jones said on Monday. "He's going to practice tomorrow. We'll see how he progresses. We're going to face a team that applies a lot of pressure to the quarterback. We have a big thing about player safety and don't want to put him in any adverse situations."
Collaros, a junior, leads the Big East in passing efficiency and yards, ranking 15th nationally. He threw for 463 yards and three touchdowns in the loss to South Florida. He has thrown eight touchdown passes in the last two games.
Syracuse (5-2, 2-1) beat then-No. 20 West Virginia 19-14 in Morgantown on Saturday. The Orange blitzed West Virginia quarterback Geno Smith, who threw three first-half interceptions and was sacked five times. Syracuse scored nine points off turnovers.
Cincinnati (3-4, 1-1) had its 13-game winning streak in the Big East snapped. The Bearcats have won the league's last two championships.
Chazz Anderson, who is also a junior, took over after Collaros got hurt and drove the Bearcats from their 29-yard line to the South Florida 15, where his fourth-down pass under pressure fell incomplete with 7 seconds left. He was 4 of 8 for 49 yards on the drive with one sack.
Anderson started two games in the 2008 season after Dustin Grutza broke his leg and Tony Pike broke his left forearm. He lost the competition for the backup job to Collaros last season, and has been No. 2 this year.
"Chazz is an individual who started a couple of games in his career here," Jones said. "I thought he did an admirable job coming in in a difficult situation last Friday night and leading the offense down."
