Overeem and Oleinik Open workouts (VIDEO)

UFC Fight Night 149 in St. Petersburg is just a day away. Saturday's night main event features a heavyweight bout between the former Strikeforce, Dream and K-1 heavyweight champ Alistair Overeem (44-17) and Russia's Alexey Oleynik (57-11-1).

Originally the Dutch had to square up against Alexander Volkov but "Drago" got withdrawn from the fight due to USADA failure.

Even though the two fighters are on the downhill of their careers, they both showcased proper speed and agility at their Open Workouts.

“The Demolition Man” last fought in November when he defeated Sergey Pavlovich via TKO in the first round. Oleynik, meanwhile, is on a two-fight winning streak defeating Junior Albini at UFC 224 and Mark Hunt at UFC Fight Night 136.
