NEW ORLEANS — When three deep passes by Darian Mensah resulted in turnovers, Tulane's long-shot hopes of sneaking into the College Football Playoff slipped away.
Greg Desrosiers Jr. caught two scoring passes and ran for a touchdown, and Memphis defeated No. 18 Tulane 34-24 on Thursday night to end the Green Wave's eight-game winning streak.
''You can't have the critical mistakes we had," said Tulane coach Jon Sumrall, whose team needed to win its regular-season finale and the American Athletic Conference title game to have any realistic chance at making the new 12-team CFP.
''There's a lot of stuff we didn't execute to our standard that we have for several games in a row now," he added. "It's very frustrating. We're all hurting, and it should hurt when you play a game like that.''
Two turnovers by Tulane (9-3, 7-1 AAC, No. 17 CFP) came on fumbles after long receptions at or inside the Memphis 10-yard line. Another came on a long pass by Mensah that was intercepted at the 2-yard line by Davion Ross, and the Tigers responded with a game-sealing drive capped by Mario Anderson Jr.'s 47-yard touchdown run.
''We could have easily held our heads down,'' Desrosiers said, referring to a pair of conference losses that dropped Memphis (10-2, 6-2) out of the AAC title picture. ''Obviously, the season didn't go as planned ... but we know what we deserve. We know what we're capable of. So, we came out here and we wanted to dominate.''
Tigers defensive back Kourtlan Marsh caused both momentum-turning fumbles, the first when he leveled Yulkeith Brown after the receiver's 40-yard catch. AJ Watts recovered at the 10 and returned it 37 yards, initiating a drive that ended with Desrosiers' 29-yard touchdown run on third-and-4 to give Memphis a 27-10 lead.
In the fourth quarter, with Tulane trailing 27-17, Mario Williams fumbled at the Tigers 9 after hauling in a 55-yard pass. Marsh recovered.
