Alabama and Tennessee carry differing degrees of momentum into Saturday’s showdown in Knoxville but the Vegas sports books aren’t siding with the Vols.

The Crimson Tide opened favored by at least a touchdown entering the 2:30 p.m. CT game in Neyland Stadium, according to VegasInsider.

FanDuel has Alabama as a 7.5-point favorite on Sunday afternoon — a number that’s gone down since first offering a spread over the summer. Tennessee was a 16.5-point underdog when the line was first set May 10.

DraftKings initially made Alabama a 7-point favorite Sunday afternoon before moving the number to 7.5 an hour and a half later.

Circa Sports has Alabama as an 8-point favorite coming off a 24-20 escape over Texas A&M.

Tennessee (6-0) is riding high coming off a 40-13 rout at then-No. 25 LSU.

The win pushed the Vols to No. 6 in the latest AP poll that saw Alabama slip from the top spot to No. 3 after the tight win over the Aggies.

Alabama has a 15-game winning streak over the Vols dating back to the 2007 season. ESPN’s College GameDay on Sunday announced it will make its first trip to an Alabama-Tennessee game since the 1995 game in Birmingham.
