TUSCALOOSA, Ala. -- Jonathan Allen returned a fumble 29 yards for a touchdown late in the third quarter to help No. 1 Alabama beat sixth-ranked Texas A&M 33-14 Saturday.

The Crimson Tide (8-0, 5-0 Southeastern Conference) moved on as the powerhouse league's last unbeaten team, getting yet another in a long string of defensive scores. Allen, a lineman, scooped up the ball after Ryan Anderson knocked it loose from Keith Ford to finally build a cushion over the Aggies (6-1, 4-1), who led 14-13 well into the third.

It was 20-14 when Allen extended Alabama's streak to 10 games with a score on defence or special teams, half the duration of a winning streak now at 20 going into an open date.

Alabama's freshman quarterback Jalen Hurts then galloped 37 yards for another score, stepping out of a defender's grasp and making a nifty move to get past another. The Tide was rolling again, a powerful encore to easy wins over ranked Tennessee and Arkansas teams.

The Aggies seemed likely to put up the biggest fight, with a defence that kept the pressure on Hurts and a handful of big runs by quarterback Trevor Knight. Then Allen and Anderson changed that in an instant.

The Tide defence sustained a big loss when safety Eddie Jackson was injured on a late punt return. Coach Nick Saban said Jackson, a senior, is out for the season with a broken leg.

Alabama racked up five sacks of Knight, who had engineered Oklahoma's Sugar Bowl upset of Alabama as a redshirt freshman with a 348-yard, four-touchdown performance. He passed for 164 and ran for 24 in the semi-rematch.

Hurts passed for 166 yards and rushed for 93 more, throwing for a pair of touchdowns while getting intercepted twice. Damien Harris rushed 17 times for 126 yards.

THE TAKEAWAY

Texas A&M: The Aggies led deeper into the game than any other 'Bama opponent, the 6:33 mark of the third quarter. Knight made some plays with his running but was also given little time to hit receivers downfield by Allen & Co. Knight threw a pick on the first play after the defence intercepted Hurts in Alabama territory. The SEC's top running team was held to 114 yards.

Alabama: Dominated the stat sheet (303 yards to 150) in the first half but settled for two short field goals and Adam Griffith missed a third. It was enough to keep it in doubt. The defence gave up back-to-back long TD drives late in the second quarter and to open the third, but delivered big plays when it had to.

POLL IMPLICATIONS

Alabama was already a near-unanimous No. 1 , but this could cause the lone holdout voter to reconsider. Texas A&M shouldn't veer too far out of the Top 10 despite the lopsided final score.
