The UFC has continued to contest titles on their Fox cards, and UFC on Fox 9 will be no different. This will be the third time in five cards that the Lightweight title will be contested on free TV as well. The problem is that it will not be TJ Grant fighting for the title like most people assumed. Instead, former Strikeforce champion Josh Thomson sill be fighting in the main event against newly minted Anthony Pettis. Thomson may only be 1-1 in his last two fights, but his scintillating knockout of Nate Diaz and Grant's injury moved him into the main event.
