TUSCALOOSA, Alabama — Johnny Manziel and No. 15 Texas A&M shook-up the national championship race by beating No. 1 Alabama, 29-24, Saturday. The Aggies (8-2, 5-2 Southeastern Conference) also might have ended the league's run of BCS titles at six years. The defending national champion Crimson Tide (9-1, 6-1), who have been No. 1 almost all season, 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. No. 3 Kansas State 23, Texas Christian 10: Collin Klein ran for two touchdowns, and visiting Kansas State bolstered its national title hopes with a victory at Big 12 newcomer TCU. The Wildcats are 10-0 for only the second time under coach Bill Snyder, and moved within two wins of likely reaching their first BCS championship game. No. 5 Georgia 38, Auburn 0: Aaron Murray passed for 208 yards and three touchdowns, freshman tailbacks Todd Gurley and Keith Marshall each ran for more than 100 yards, and the visiting Bulldogs returned to the SEC championship game. No. 7 Florida 27, Louisiana-Lafayette 20: Jelani Jenkins returned a blocked punt 36 yards for a touchdown with 2 seconds remaining, and host Florida rallied in the closing minutes. The Gators (9-1) scored twice in the final 2 minutes to avoid the biggest upset in school history. No. 9 Louisiana State 37, No. 23 Mississippi State 17: Zach Mettenberger passed for 273 yards and two touchdowns, and host LSU kept alive faint hope of a Southeastern Conference title. No. 10 Clemson 45, Maryland 10: Tajh Boyd threw for 261 yards and three touchdowns in the host Tigers' sixth straight win and 12th in a row at Death Valley. Syracuse 45, No. 11 Louisville 26: Ryan Nassib threw for 246 yards, Jerome Smith ran for 144 yards, and Syracuse handed Louisville its first loss. Playing in the last home game of his career, Nassib directed an offense that gained 524 yards. Nassib was 15-for-23 and passed Donovan McNabb for second place on the school's career passing yards list behind Marvin Graves. Elsewhere it was: No. 12 South Carolina 38, Arkansas 20; No. 16 Stanford 27, No. 13 Oregon State 23; No. 14 Oklahoma 42, Baylor 34; No. 19 Texas 33, Iowa State 7; No. 21 Southern California 38, Arizona State 17. — Agencies
