LOS ANGELES -- Shawn Tolleson suffered a left hip injury in his return from lower back surgery and had his Minor League rehab assignment put on hold, which will likely prevent the reliever from joining the Dodgers once rosters expand Sept. 1.
Tolleson developed a hip issue as he was coming back from surgery in April to repair a herniated disk in his lower back. The right-hander tried to pitch through the hip injury and made one rehab appearance with Class A Rancho Cucamonga on Aug. 14. But Tolleson's hip wasn't getting better and he's no longer throwing off a mound.
"He's getting slowed down," Dodgers manager Don Mattingly said. "I haven't heard that he's been shut down for the year. I just heard that he's on hold."
Tolleson, 25, made one appearance with the Dodgers this season before going on the disabled list. He appeared in 40 games with Los Angeles last year, striking out 39 in 37 2/3 innings with a 4.30 ERA.
