The former UFC heavyweight champion has one more fight on his Strikeforce contract, and that fight will be against unknown Nandor Guelmino.
The native of Austria has an 11-3 record with six wins by way of submission. Will the unknown Guelmino pull off the victory, or will Barnett get a much-needed victory and get in to the UFC?
Let's break down the fight and see who will win this heavyweight tilt.
This is the hardest aspect to break down in this fight. Barnett has won only one fight by knockout in 31 victories, and that was over Pedro Rizzo at the first Affliction show in 2008. Guelmino has never won a fight by knockout in his 11 victories.
Barnett has been knocked out only one time in his career, and that was by Pedro Rizzo in the first fight they had in 2001. "The Warmaster" has also faced the likes of Mirko Cro Cop and Antonio Rodrigo Nogueira.
Guelmino began his martial arts background in taekwondo as a youngster and is a black belt.
Barnett has been known in past fights to stand and trade for a while before taking the fight to the ground. The only high-caliber fight of Guelmino's career was against kickboxing legend Semmy Schilt, who knocked him out in the first round.
Barnett is one of the premier grapplers in the sport. In his last fight, Barnett lost to Olympian wrestler Daniel Cormier. Cormier was able to dominate Barnett in the grappling department. Barnett is a catch wrestler and has also dabbled in the world of professional wrestling in Japan.
Guelmino has no grappling background to speak of. Barnett should be able to impose his will by getting Guelmino against the cage and taking him down to the mat.
Josh Barnett is known as a submission artist. He has won 19 of his 31 victories via submission. The California native has submitted the likes of Mark Hunt and Sergei Kharitonov in his career.
Guelmino has six of his 11 wins by submission. He hasn't faced a fighter of this caliber, though. Should the fight go to the ground, look for Barnett to try to lock in a submission very quickly.
X-Factor for Barnett: Focus
It's easy to see Barnett looking past Guelmino. After all, he doesn't know what the future holds after this fight. He could win the fight and still not get in to the UFC. If he loses, a return trip to the Octagon is even less likely.
"The Warmaster" has faced some of the top heavyweights in the world. While he won't publicly state it, it would be hard to believe he doesn't want to return to the UFC.
X-Factor for Guelmino: Fast Start
A fast start is a key to most fights, but for Guelmino it is a must. He has never faced a guy like Barnett and needs to make Barnett respect him early in the fight.
If he can do that, we could be in for a fight.
Does Guelmino have a chance? Of course he does. Every fighter has a chance when they step inside the cage. Barnett has the advantage in every aspect of this fight, though.
Barnett will set up his takedowns with his striking. Once the fight gets to the ground, Guelmino will be in Barnett's domain. Experience and the ground game will be too much for Guelmino.
Winner: Josh Barnett by first-round submission.
