The UFC have added two huge heavyweight fights for their next FOX show, with four careers set to be defined by the event.
Alistair Overeem will face off against Stefan Struve and Matt Mitrione will meet Gabriel Gonzaga at the US Airways Center in Phoenix, Arizona in December as the heavyweight division looks to be shaken up some more.
Although the heavyweight division is light on talent at the moment, losses for them could spell the end of their UFC careers at very least.
Overeem vs. Struve
Alistair Overeem has suffered perhaps one of the biggest drops in hype in the history of MMA as the former kickboxing World Champion has been on the receiving end of three brutal KO losses in recent years.
He dispatched of former UFC Heavyweight champion, Brock Lesnar with ease when they fought but since then Antonio Silva, Travis Browne and Ben Rothwell have all had their way with the Dutch fighter.
A win over Frank Mir in February has been the highlight of a miserable two years for him.
A loss against Struve, especially another knockout loss would all but end his time in the UFC and whether it's by order of Dana White or of his own jurisdiction, the writing is on the wall heading into this fight.
On the other hand, Struve is returning from a heart condition that seen him sidelined over 18 months and forced him out of a proposed clash with Matt Mitrione in July at UFC 175.
Struve is the tallest fighter in the UFC at 7ft and share the longest reach in the organisation with Jon Jones, so expect to see him exploit that against Overeem.
If Struve is to lose, then with his heart condition playing a factor as well, the current #14 could be forced out of the sport for reasons other than just back-to-back losses.
Either way - only one Dutchman will be flying high after this, while the other has a tough decision to make.
Mitrione vs. Gonzaga
As for Mitrione and Gonzaga, the pressure will be on Mitrione to produce a result against a 'name' opponent after three previous attempts have seen him falter.
The former-NFL lineman and Ultimate Fighter alumni has lost in fights with Cheick Kongo, Roy Nelson and Brendan Schaub, yet has been great a clearing through the best of the rest.
Against Gonzaga, he has a chance to finally break into the top 15 ranked fighters and prove himself in the division.
At 36, time may be against him for a serious title run but if the likes of Mark Hunt and Nelson have proven anything, it's that the UFC fans don't care for age and love a knockout artist like Mitrione.
Gonzaga is in a boat similar to Mitrione, in that he's able to put away decent opponents but can never make that leap in competition and falters against the bigger names.
He's currently ranked #12 and although he has fought for the UFC title before, that was seven years ago and since then, he has become 'the gatekeeper' for most of the more technical fighters in the UFC.
With KO losses to the likes of Travis Browne and Junior dos Santos, Mitrione will like his chances of finishing Gonzaga but never is ever certain.
If Mitrione wins, he'll be getting somewhere finally and make even take Gonzaga's place. For Gonzaga, a win would be great at re-establishing his role in the UFC and keeping the rest out of the top 10.
