The AFL requires players who suffer a suspected concussion or show concussive symptoms during a match to be sent for a formal medical test. This off-field test – known as SCAT5 – takes 15 minutes and involves a club doctor identifying red flags such as loss of consciousness and vomiting, checking for signs of concussion like disorientation, and performing cognitive and concentration tests.
I think you could say that he could have suspected that he had concussion.
