John Cena vs. Samoa Joe was originally scheduled for last night’s RAW, however those plans obviously changed.

On last night’s episode of the Wrestling Inc. Podcast, Joe faced Cena at WWE RAW live events on Friday and Saturday, however Joe wasn’t at Sunday’s show and Cena worked with Bray Wyatt instead.

PWInsider reports that Joe reportedly suffered some sort of knee injury at one of the live events over the weekend. Joe could be out of action for at least four weeks. WWE has yet to acknowledge the injury as of this writing.

Joe teamed with The Miz to face Cena and Roman Reigns on last week’s episode of RAW, and was a part of the Fatal 4-Way SummerSlam main event the night before.
