The winner figures to earn a shot at the light heavyweight title. Also on the line will be Big Ten bragging rights.
Evans (21-1-1) wrestled collegiately at Michigan State. Davis (9-0), who wore a Penn State singlet to the weigh-in for the big fight earlier this week, is a former Nittany Lion.
No word on if the Land Grant Trophy is being flown into the Windy City for the occasion.
The two never met on the mat in college as Evans (32) is significantly older than Davis (27), at least in fighting terms.
Evans, nicknamed Suga, is a former UFC light heavyweight champ who has fought only once since May of 2010. He knocked out a washed up Tito Ortiz in UCF 133 last August.
Davis, aka Mr. Wonderful, was supposed to fight Evans that night in Philadelphia but had to pull out due to a knee injury. Ortiz took the fight on short notice. Davis' last fight was in March of 2011, when he decisioned veteran Antonio Rogerio Nogueira.
In the days leading up to this fight, Evans tried to start a war of words, calling Davis a boy, belittling his wrestling style and even making fun of his looks. Davis, always smooth in interview situations, laughed it off and even mocked Evans a bit, saying, The winner of this fight will fight for the title. But in the event I hit him too hard and break my hand it might lead to someone else getting the title shot first.
Video of the pre-fight press conference is available online. The verbal sparring comes across more as hype than anything else.
I'm not saying he's not ready for [this] stage, Evans told Fox Sports. I'm saying he's not ready to fight me.
I have not animosity toward this guy or anybody else I'm gonna fight, Davis told Fox Sports. I'm going to do the same job, as vigorous as I would whether I like you or don't like you.
Jon Jones (15-1-0) is the current UFC light heavyweight champ.
