The Bulls host the Sharks at Loftus Versfeld on Saturday (kick-off 19:00) in a fixture that is rich in history.
What happened at Kings Park in 2007, when the Bulls won the first of their three Super Rugby crowns, still haunts Sharks fans to this very day.
19-13 up after the hooter had blown in that year's tournament final, the Sharks then imploded with Bryan Habana scoring a famous try before Derick Hougaard kicked the winning conversion to leave Bulls fans elated and Durbanites devastated.
The Sharks have never won Super Rugby and with that tournament now almost certainly over, they will have never come closer than they did in 2007.
Super Rugby Unlocked, however, has given South Africa's premier franchises one final opportunity to bag some silverware under the banner of what has been the premier southern hemisphere franchise competition for 25 years now.
Jake White, former Springbok and Sharks coach, is now in charge at Loftus while Sean Everitt is in his first season at the helm of the Sharks.
Here, Sport24 looks at the history between the sides.
The Bulls have dominated this fixture historically, winning twice as many times as the Sharks.
Before the Sharks' 23-15 win in Durban earlier this year, 2014 was the last time they beat the Bulls in Super Rugby which meant a run of nine matches without a win.
