The Toronto Raptors already looked to have their hands full with a matchup against the streaking Lakers in Los Angeles on Sunday. Then two of their top performers went down with injuries in the club's victory over the New Orleans Pelicans on Friday. Guard Kyle Lowry, the Raptors' second-leading scorer at 21.8 points per game, sustained a fracture in his left thumb in the first quarter, and forward Serge Ibaka went down with a severe right ankle sprain in the second quarter.
