Then again, the last time either former champion won a fight was Jan. 28, 2012 -- when Evans defeated Phil Davis via unanimous decision.
Evans and Henderson are set to meet in a high profile light-heavyweight contest at the MTS Centre in Winnipeg, Manitoba, on Saturday. All 22 fighters set to compete on the pay-per-view event successfully made weight during Friday's official weigh-in.
Earlier in the week, UFC president Dana White admitted that "statistically" it would be difficult for the loser of this weekend's main event to reach a title fight.
Evans (17-3-1), a former UFC light-heavyweight champion, weighed in at the 206-pound limit. The 33-year-old is looking to rebound from back-to-back losses for the first time in his professional career.
Henderson (29-9), who has held titles in Pride and Strikeforce, came in at 204 pounds. His title hopes suffered a setback in February, when he dropped a unanimous decision to Lyoto Machida at UFC 157.
"Dan is one of my favorite fighters," Evans said. "I love the opportunity I get a chance to fight him. Tomorrow night, we're going to give it all we've got and I'll be on top."
In the co-main event, fan favorite Roy Nelson (19-7) will look to extend his win streak to four against fellow heavyweight Stipe Miocic (9-1). Nelson came in at 260 pounds at Friday's weigh-in, significantly heavier than Miocic (243).
The main card also features a women's bantamweight matchup between Canadian Alexis Davis (13-5) and Rosi Sexton (13-2). A heavy favorite to win the bout, Davis weighed in at 134 pounds. Sexton came in at 135.5 pounds.
