I found this on Flo.... "And Ke-Shawn Hayes gets a takedown in sudden victory over Malik Amine! OR DOES HE? They'll review. And we are head to the tiebreakers on Mat 5! After review, time was out. Ke-Shawn will start on top first, but Amine will get the reversal with very little time left on the clock, so little that Ohio State is going to challenge. The call is confirmed, and Amine gives up a stalling on his turn on top, making it 5-4. Hayes frees his leg, finishes the reversal off a scramble to win 6-5! Great match by the two rival schools."
So that means Ohio State lost TWO challenges in the first round and should only have 1 left for the remainder of the tournament
