After his impressive victory at UFC Fight Night: Rodriguez vs. Lemos, Grant Dawson went on to call out UFC veteran Tony Ferguson for a showdown.

In his post-fight interview with Daniel Cormier, Dawson said that if the fight against Ferguson did not come to fruition, it would be because 'El Cucuy' turned him down.

"I just wanna say what an honor it is to be taking Tony Ferguson's spot in the top [15] and if Tony wants to come and try to get that spot back, I am more than willing to defend my newly ranked number 15 position against Tony Ferguson next. If me or Tony Ferguson fight anybody else but each other, just know, that he turned me down."

You can watch the full post-fight interview below:

Ferguson is currently going through a rough patch in the UFC. The 38-year-old has failed to secure a win in his last five outings and was also finished in his last two UFC appearances.

It would appear that the former interim lightweight champion is past his prime. So, getting matched up against a young fighter who is on an incredible run might not be a good idea for Ferguson.
