Weaver put on DL; Kuo activated

The Los Angeles Dodgers placed reliever Jeff Weaver on the 15-day disabled list before Thursday night's game at Cincinnati because of a strain on the right side of his lower back. The move cleared a roster spot for reliever Hong-Chih Kuo, who was activated from the 15-day DL for the first time this season after overcoming left elbow soreness.

Weaver faced one batter on Wednesday night, entering to start the eighth inning and getting Jonny Gomes to ground out. Weaver immediately appeared to be in pain after Gomes' at-bat, and when manager Joe Torre and assistant trainer Todd Tomczyk went to the mound to check on him, Weaver was immediately removed.

Weaver had appeared in nine of the Dodgers' first 14 games this season, allowing three runs on five hits over a total of 5 1/3 innings. Torre expressed concern during the team's recent homestand, at a point when Weaver had pitched in six of the Dodgers' first seven games, that the veteran right-hander was being used too frequently.

The 27-year-old Kuo was 2-0 with a 3.00 ERA in 35 games for the Dodgers last season.
