The unofficial season premiere of "Monday Night Raw" starts on Monday following a star-studded and memorable "WrestleMania 31" from Levis Stadium with a capacity crowd of 76,976 fans from all 50 states and 40 countries. Many of those fans will be present tonight for perhaps one of the best shows of the year: "The Raw After WrestleMania."

The biggest highlight of Sunday night was Seth Rollins cashing in his Money in the Bank briefcase and successfully pinning Roman Reigns to win the WWE World Heavyweight Championship. Rollins' cash-in allowed the one-on-one match between Reigns and Brock Lesnar turn into a triple-threat match. Lesnar didn't get pinned, therefore, expect Lesnar and Paul Heyman to demand a rematch or justice for the loss.

With Rollins' win, he became the first WWE Superstar to cash-in his briefcase as "WrestleMania," the first NXT Champion to win the main WWE title and the first wrestler born after "WrestleMania 1" to capture the championship.

The Authority had a fairly positive night with Triple H pinning Sting and Rollins leaving Levis Stadium with the WWE World Heavyweight Championship. However, things went sour when Triple H and Stephanie McMahon were confronted by The Rock and UFC Women's Bantamweight Champion Ronda Rousey. Expect Triple H and Stephanie to figure out a battle plan against Rousey and The Rock.

Rusev's undefeated streak came to an end on Sunday night as John Cena pinned the Bulgarian Brute for the United States Championship. Cena's win came at Lana's expense who was accidentally hit by Rusev, but the latter showed no remorse for the Ravishing Russian. Monday night should reveal the status between Rusev and Lana.

Daniel Bryan also won a singles-title in the form of the Intercontinental Championship. It is Bryan's first win for the Intercontinental Championship, but former champion Bad News Barrett will surely seek to enact his rematch clause. Dean Ambrose has made it his mission to win the title since late January -- don't expect him to be out of the picture suddenly.

On the Divas Division, The Bella Twins suffered a loss against frenemies AJ Lee and Paige. Lee managed to have Divas Champion Nikki Bella submit to the Black Widow, and the victory could elevate Lee in line for a championship match tonight or for "Extreme Rules."

The "Raw After WrestleMania" is also a big show for potential debuts and announcements. Last year's show saw the debut of Paige and Rusev and announcements of Adam Rose and Bo Dallas. Will the next crop of NXT superstars make their debuts or initial promos tonight?

"Monday Night Raw" starts at 8 p.m. EST on the USA Network.
