He is hurt, possibly from the end of the Andonian match (he received a leg hit to the leg in the final scramble). Early in his second match, there was a high-speed scramble that ended off camera, followed by the Cornell corner coming over. The ref then gave the "fist to the forehead" sign indicating concussion protocol, which was not initiated. It was pretty clear that there was a head issue after that. Really surprised he was allowed to continue. I'll be surprised if he goes to the Collegiate Duals in two weeks.
He does not have a conditioning problem, that is clear.
