A fight can be a pressure cooker all by itself, but it’s often the reputations, ego, or career that can turn the heat up even further. Four who have more to lose than usual this Saturday:

Mark Coleman: The 44-year-old has posted up just two fights -- both losses -- in the past three years. His stature in the sport is cemented, but future paychecks in the UFC may depend on his performance against a younger, fresher Stephan Bonnar.

Brock Lesnar: Wins against Heath Herring and Randy Couture were impressive, but neither can be considered in the prime of their careers: Lesnar will either avenge a loss to Frank Mir or find that he’s not quite ready for the top level of competition. His is an arrogance and swagger that can’t really afford another loss to Mir.

Michael Bisping: Has talked a sanitation truck full of sh-t leading into his fight with Dan Henderson: Anything less than a knockout -- which would be a first for Henderson -- will feel a little underwhelming.

Mac Danzig: The “Ultimate Fighter 6” lightweight winner is 0-2 in his formal UFC career, having been outhustled by Clay Guida and rendered short of breath against Josh Neer. With the UFC recently cut-happy, a loss to Jim Miller could have him seeking alternative employment.
