UFC Fight Night 64 Gabriel Gonzaga vs. Mirko Cro Cop full fight video preview

Ultimate Fighting Championship (UFC) will make its debut in Poland later today (Sat., April 11, 2015) from inside the Krakow Arena with UFC Fight Night 64, headlined by the heavyweight rematch between Gabriel Gonzaga and Mirko Filipovic, live on UFC Fight Pass.

For Filipovic (30-11-2, 1 NC), this will be his first appearance inside the Octagon in over three years. He ended his first run under the ZUFFA banner with three consecutive knockout losses, but the one that probably stings the most -- for fans as well as for "Cro Cop" -- is the head kick finish he suffered to Gonzaga at UFC 70.

Watch that entire fight here.

"Napao" (16-9) was unable to parlay that win into something bigger and has since struggled to stay consistent over the last eight years. The Brazilian -- five years younger than the Croat at age 35 -- has dropped seven of his nine losses by way of knockout.
