Much depends on Solis shape. If motivated to get into shape, he;s the second best active boxer behind Wlad.
Solis is fighting Thompson, a fighter that Wilder refused to fight. Vladimir Klitschko knocked Thompson out two times. Thompson is old now, but we will see. If Solis gets knocked down he will blame it on his knee once again. Solis had to struggle with Austin whom Vlad knocked out in the second round. Vitali knocked Solis out in the first round with a right hook to the temple, Solis went down before his knee was injured.
