John Cena may be defending his U.S Title on Monday's Raw from Buffalo in the return of the U.S. Open Challenge, as the following teaser from WWE.com mentions:

"One night after reclaiming the United States Championship from Seth Rollins at Night of Champions, John Cena defended his star-spangled prize on Raw, sealing a victory over The Architect with an Attitude Adjustment. Now that Rollins has already used his guaranteed rematch for the prestigious title, will Raw bring the return of Cena’s U.S. Open Challenge? If so, who is bold enough to face The Champ?"
