This is the closest we have to an official confirmation: Sanderson to Compete in WTT | Forum Topic | Flowrestling

Al Bevilacqua is definitely in-the-know (as former national team coach and founder of Beat the Streets), but there are still conflicting accounts about this. Cael is keeping it as close to the chest as possible and I wouldn't be surprised if hadn't made a decision until recently.

Al's kids wrestled at PSU so he might have an in there but all the little birdies in SC keep telling me that he isn't going to say anything while he is wrestling hard every day with Cunningham to get down to 84kg.
