TUSCALOOSA, Ala. — Johnny Manziel and No. 15 Texas A&M shook-up the national championship race by beating No. 1 Alabama 29-24 on Saturday.

The Aggies (8-2, 5-2 Southeastern Conference) also might have ended the league’s run of BCS titles at six years.

The Crimson Tide (9-1, 6-1) didn’t go quietly.

AJ McCarron nearly pulled off a second straight scintillating comeback. He threw one touchdown pass and motored the ball downfield before Deshazor Everett stepped in front of his fourth-down pass at the goal line with 1:36 left.

Manziel passed for 253 yards and rushed for 92 and led the Aggies to a 20-0 first quarter lead.

Alabama, the nation’s top scoring defense, forced a punt with less than a minute left, but was called for offsides, giving Texas A&M a first down and a chance to run out the clock.

McCarron breathed new life into Alabama with a 54-yard touchdown pass down the left sideline to freshman Amari Cooper to make it 29-24 with 4:29 left.
