As we saw last night, Shane McMahon took a nasty spear from Roman Reigns when attempting a coast-to-coast. Shane looked to be in rough shape and was helped to the back. Word is that Shane was indeed legitimately hurt, and was treated backstage, although it's unknown whether he suffered a concussion. He was said to be in a lot of pain when leaving the Air Canada Centre last night.
It's unknown at this point whether Shane will be on SmackDown tomorrow night.
