TUSCALOOSA, Ala. (AP) — Jalen Milroe passed for two touchdowns, Jihaad Campbell returned a fumble for a score in the fourth quarter and No. 11 Alabama uncorked 27 straight second-half points in rallying for a 34-20 victory over No. 17 Tennessee on Saturday.

With its national title hopes on the brink, Alabama (7-1, 5-0 Southeastern Conference) turned in its most dominant half of the season. And it came against a border rival who had helped end ‘Bama’s championship aspirations a year ago.

The comeback was fueled by big plays from Milroe and tailback Jase McClellan and a defense that smothered Joe Milton III and the Volunteers (5-2, 2-2) after the half and even provided the decisive TD.

Cambell took a scoop-and-score 24 yards midway through the fourth quarter after Chris Braswell knocked the ball loose from Milton.

The loss dealt a big blow to the SEC East chances for the Vols, who had built a 20-7 halftime lead with a huge start from Milton.

Their chances of a first win in Tuscaloosa in 20 years rapidly evaporated. The Vols had ended 15 years of frustration against the Tide, 52-49 a year ago on a last-play field goal.

Milroe completed 14 of 21 passes for 220 yards, with a 46-yard touchdown less than a minute into the second half and an earlier 10-yarder to Jermaine Burton. McClellan ran 27 times for 115 yards and a touchdown.

Milton was 28 of 41 for 271 yards — including 175 by the half — and two touchdowns. He also gained 59 rushing after completing his first nine passes.

Alabama turned Vols coach Josh Heupel's second failed fourth-down gamble shy of midfield territory into its first lead. McClellan bounced outside and ran untouched for a 5-yard touchdown.

The Tide had a chance to make it a two-score game in the fourth quarter but had to settle for Will Reichard's 50-yard field goal for a 27-20 lead with 8:17 left. The defense delivered the knockout blow.

Squirrel Wright sprawled out for a 39-yard touchdown on the opening drive and finished with 10 catches for 111 yards. He had eight for 105 by halftime, though.

THE TAKEAWAY

Tennessee: The Vols looked like a different offense in the first half, keeping the Tide off-balance. Milton turned things around after Texas A&M held him to 100 passing yards. Heupel's fourth-down gambles and failures in the red zone cost the team.

Alabama: Yet another slow start left Alabama down 13-0 and outgained 187-36 in the first quarter. The Tide looked like a complete team in the second half, though. It was a big bounce-back from second-half struggles against Arkansas.

POLL IMPLICATIONS

Alabama could well return to the Top 10 for the first time since losing to Texas — unless voters only saw the first half. The Vols won't likely fall too far.
