TUSCALOOSA, Ala. — Jonathan Allen returned a fumble 29 yards for a touchdown late in the third quarter Saturday to help top-ranked Alabama beat sixth-ranked Texas A&M, 33-14.

The Crimson Tide (8-0, 5-0 Southeastern) 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 defense 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.
