#2 Return at TLC

Similar to what we saw at WrestleMania, with John Cena unsure whether The Undertaker would show up for the challenge or not, an angle can be set up with Corbin and Strowman.
Even with the fans almost certain that Strowman would show up, it would add a different feeling to what has been going on RAW with Strowman constantly running around knocking people over and chasing people.

As Corbin would make it to the ring sure that Strowman will be unable to show up for his match, handing a forfeit victory to the Acting General Manager, Strowman could emerge to attack him.
After the bell rings, Strowman could manhandle Corbin and get a squash victory over his competitor just like Lesnar earned one over Strowman at Crown Jewel.
A squash victory would protect Braun Strowman from worsening his injury while coming out as more dominant and ending Corbin's reign as the Acting General Manager.
Alexa Bliss could then be announced RAW’s new General Manager with immediate effect after the match by Stephanie McMahon.
