Saturday nights are heating up. WWE Saturday Night's Main Event returns for its fourth primetime special since being revived last year. This time, the world heavyweight title is on the line, plus CM Punk and Sami Zayn scrap with Seth Rollins and Bron Breakker.

Sabu revolutionized hardcore wrestling in ECW throughout the 1990s and was involved in a number of classic matches with the likes of Taz, Mick Foley and Rob Van Dam. A former ECW Tag Team champion, ECW World Television champion and ECW World Heavyweight champion, he is widely regarded as one of the most decorated competitors in company history.

More matches are expected to be announced Friday on SmackDown, from where we'll likely learn about Undisputed WWE Champion John Cena's next challenger. Cena, who won his match against lifelong rival Randy Orton at Backlash, aims to retire with the championship, "ruining wrestling for everyone" in the process.
