The Big Show went in for a check-up last Friday and was still not cleared to return. Show had another check-up yesterday before RAW and was finally cleared to return. Despite that, the show had already been re-written numerous times throughout the day and they opted not to use him as it was simply too late. It’s possible they’ll run an angle at tonight’s WWE SmackDown tapings or next week’s RAW but he is now ready to go.
