They definately will, especially because this one was so controversial (with BJs possible rib problem) added to the fact that they're now 1-1 (Rubber Match time..woo).

However, Penn is 0-2 in the UFC since his return, so expect him to fight Diego sometime soon for number one contender (Right after Hughes v GSP if Hughes wins, or after Hughes' rematch if GSP wins...plus the winner of The Ultimate Fighter 4 will get a title shot against Matt/GSP).

So long story short, he'll definately get one, but he'll have to beat Diego or GSP first if Hughes wins, or he'll fight Hughes for the rubbermatch if he loses both the title defense AND his rematch vs GSP.
