Part of challenger

Diego Sanchez'

strategy seemed to be to take out one of UFC lightweight champ

BJ Penn's

legs. But that played right into Penn's game plan.

"It's a blessing when a guy grabs my leg," Penn said, "because I know that's my chance to hit him. They're usually running away, and I've got to wait to hit them. If he grabs the leg, I can just keep hitting him."

Penn used the counterpunching to retain his UFC lightweight championship with a fifth-round TKO of Sanchez in the main event of UFC 107 Saturday in Memphis, Tenn.

Referee Herb Dean, with the advice of the ringside doctor, stopped the fight at 2:37 of the round after Penn's kick caught Sanchez, opening a gaping gash above the challenger's left eye.

UFC president Dana White said Sanchez was taken to a hospital, adding, "He was about as busted up as I've ever seen a guy."
