Miami rebounded from a 35-33 upset loss to Ohio, which came into the game with just one win in eight games.
Gabbert completed 21 of 28 passes for 351 yards and did not throw a turnover. Sorenson, who set a school record with 283 yards on 14 catches, caught five more for 112 yards.
The RedHawks (5-5, 4-2 Mid-America) forced a Buffalo fumble on its first offensive series and Gabbert wasted no time getting the RedHawks into the end zone with on a flea flicker to a wide-open Sorenson. Gabbert hit Mac Hippenhammer from 14-yards out to start the second quarter, then found Andrew Homer and Jalen Walker for touchdowns in the third quarter.
Kyle Vantrease was 11 of 20 for 151 yards for the Bulls (4-6, 2-4), but threw an interception and was forced into a fumble after running for two yards on Buffalo's first series. Dylan McDuffie carried 20 times for 91 yards.
