Oliver, a 5-foot-8 junior from Miami, Fla., is the biggest concern for Buffalo. He is the offensive workhorse for the Bulls (1-2) with 426 yards and three touchdowns on 71 carries this season. He is averaging 6.0 yards per carry with a long run of 36 yards.
Buffalo has not played since that loss to Kent State and Oliver missed the second half after being injured. The Buffalo News reported that Oliver played the first half but was in street clothes after halftime. He had 77 yards on 16 carries before being sideline.
Without Oliver, Buffalo coach Jeff Quinn was forced to dip down to the No. 3 and 4 running backs on his depth chart. Oliver's backup, James Potts, was lost for the season when he tore an ACL in a win over Morgan State. Brandon Murie, a junior, and Devin Campbell, a true freshman, shared the carries in the second half against Kent State.
"[Oliver] is going to be day-to-day," Quinn said on Monday's Mid-American Conference coaches' conference call. "We have an outstanding medical staff that knows how to get these guys back on the field. He really banged up his leg. Not sure exactly where he's at in terms of today. But we've just got to keep a close eye on it and see how he's progressing.
"Fred Lee has his hand banged up and it's in a splint. He's going to miss this week's game. Boomer Brock has a chest injury that's probably going to require some surgery."
Oliver rushed 23 times for 84 yards against UConn last season in a 17-3 win for the Huskies at University of Buffalo Stadium.
Buffalo passed for 193 yards against UConn but quarterback Chazz Anderson is gone. Junior Alex Zordich starts and has completed 34 of 67 passes for 477 yards. Buffalo ranks 72nd in total offense in this week's NCAA statistics, but that's better than UConn at 106th.
UConn announced the Big East opener at Rutgers on Oct. 6 will begin at noon and be televised on ESPNU.
