UFC heavyweight Alistair Overeem has had a distinguished career. The PRIDE, DREAM, Strikeforce, K-1 and UFC veteran has almost seen it all (a UFC title shot notwithstanding), but it's uncertain exactly what the future holds for the former kickboxing and MMA champion.

Up first: a long-anticipated bout with former UFC heavyweight champion Junior dos Santos at UFC on FOX 17 in Orlando, Florida on Saturday. That bout will serve as the co-main event of the fight card.

After that? Well, it's anyone's guess.

As Ariel Helwani first reported on UFC Tonight on Wednesday, Saturday's bout is the last of Overeem's current contract with the UFC. After Saturday's contest, the Greg Jackson-trained heavyweight will attempt to test his value on the open market.

Overeem is not the only fighter to try this in an attempt to maximize their value. Fighters like Aljamain Sterling and Ben Henderson are currently in renegotiating periods. Other fighters such as Phil Davis, Gilbert Melendez, Josh Thomson, Josh Koscheck and Chris Weidman have also attempted to fight through the entirety of their UFC contracts, some staying with the promotion, others moving on to Bellator.

There is no word on Overeem's preference for where he'd like to end up. He has, however, worked with Bellator President Scott Coker when the promoter was in charge of the now-defunct Strikeforce organization.
