In the Trojans' stunning 24-23 loss to Stanford, John David Booty -- who threw four interceptions -- played the final 2? quarters with a broken middle finger on his throwing hand. The fifth-year senior is questionable for Arizona on Saturday. "I don't know if I'll play," he said following the game. At halftime, Booty had his hand X-rayed, and the exam revealed the fracture. He is believed to have suffered the injury following through on a second-quarter pass. "I want to play. I want to compete and fight," Booty said, according to the Orange County Register. "No way were they going to pull me out of that game ... even if there were times I probably wasn't at my best because of it. "Look at [Brett] Favre, look at those guys. They don't hardly ever play healthy."
