Bucks guard Luke Ridnour injured his right wrist late in the first quarter and had to leave the game to be examined on Sunday night at the AT&T Center. Ridnour apparently caught his hand in a jersey as teammate Ekpe Udoh screened for him and San Antonio guard Patty Mills defended. After Ridnour was examined in the locker room, the injury was termed a sprained right wrist and the Bucks said he would not return to the game. San Antonio grabbed a 53-38 lead and pushed ahead late in the first quarter with a 15-0 run to outscore the Bucks, 29-16, in the period. Gary Neal entered the game off the bench in the second quarter, the first appearance for the Bucks guard since Jan. 4 in Phoenix. Neal played the past three seasons with San Antonio and was a key reserve on the Spurs team that reached the NBA Finals last season, losing to Miami in seven games. Mills gave the Spurs a spark with 12 points off the bench, including 5 of 7 shooting. Cory Joseph started at point guard in place of Tony Parker, out with a shin bruise.
