HOUSTON -- Ronny Cedeno was scheduled to begin his rehab assignment with Triple-A Indianapolis on Sunday, and manager Clint Hurdle said it's possible Cedeno and Steve Pearce could return to the Pirates for the weekend series against the Cardinals.
Pearce, who is hitting 5-for-14 since going down to Indianapolis on Thursday, is recovering from a partially torn right calf, while Cedeno suffered a concussion while attempting to break up a double play.
"From what we saw here in three days, [Cedeno] seemed alert, he seemed crisp, [he was] running [with] no problems ... [he had] first-step quickness," Hurdle said. "Get him in some games, and we'll see."
Hurdle said he'd wait for about four rehab starts to determine whether he thinks Cedeno is ready.
"If the at-bats aren't good and he's rusty and it's just not feeling right, we're not going to push him back until he's ready," Hurdle said. "I think Pearce would be another guy along those lines, same type of timetable."
Hurdle said it's difficult to determine a timetable for concussed players.
"Some guys have bounced back in four days, and [Justin] Morneau took a year," Hurdle said. "There was a guy that, if you look at the videotape of that collision, it doesn't look much more significant than Ronny's. But I think that's given everybody a much better perspective for the people who say he hardly even got hit."
