With college wrestling, there are absolutely no sure things.   #1 Bo Nickal brought his undefeated record to Indiana for a match against #12 Nate Jackson of Indiana.   He didn't leave with it.

#12 Nate Jackson won an absolutely wild bout against Bo Nickal.  The match began as you'd expect.  It was a beautiful throw by for Nickal for 2.  Jackson earned an escape to make it 2-1.  Bo immediately went double overs for a throw in the transition and got caught on his back for 6 to end the first.  The period ended 6-2 Jackson.  

In the 2nd Bo took bottom and earned an easy escape. Bo was on the attack the entire 2nd and earned a stall warning.  Despite getting in deep he wasn't able to finish against Jackson.  Jackson used his length well to prevent the finishes.  In the 3rd it begins 6-3 Jackson who took neutral.  Right away Bo goes bodylock for 2 to make it 6-5.  

After an escape Bo continued to fire off attack after attack getting in deep on a single leg. Bo was so close to a finish on the edge the official briefly held up 2 before waving it off.  It went to review where the call was upheld.  Bo was down 2 late, continued to attack but couldn't but Jackson down for 2.  

Jackson was hit for stalling late but it was irrelevant as Bo fell one point short.  Jackson was the winner, 7-6.
