As noted, Bray Wyatt rolled his ankle during Tuesday's WWE SmackDown main event but finished the match. After the injury, the referee threw up the dreaded "X" symbol but Wyatt clearly didn't want to stop and didn't want help from trainers.
Dave Meltzer confirmed on wrestling Observer Radio that Wyatt sprained his ankle. Wyatt was still planning on working weekend WWE live events as of Wednesday morning. If he does miss this weekend's matches, that could indicate that the injury is serious as he was intent on wrestling this weekend. Meltzer also confirmed that WWE wanted Wyatt to stop the match on Tuesday night but he refused.
