Rollins, who has been on the 15-day disabled list with a strained right calf since April 13, flew from Florida to Philadelphia on Sunday to rejoin the team.
Assistant general manager Scott Proefrock said Rollins will be evaluated Monday. Assuming that goes well, Rollins will be activated before the series opener against the Pittsburgh Pirates at Citizens Bank Park.
Rollins, who hit .391 in 23 at-bats before getting hurt during pregame warmups April 12, has played in one rehabilitation game with Class A Clearwater, plus a few extended spring training games. Reports have been positive.
"What we missed is that Jimmy is an all-around player," manager Charlie Manuel said. "You can't put his value in one area. He can run. He can throw. He's a switch-hitter. He can steal bases. He can make deep throws on the cutoff. He can play defense. He's an all-around player. He's one of the better players in the league. Yeah, we've missed him. Our lineup is better with Jimmy in there."
Infielder Wilson Valdez, who has hit .234 in 47 at-bats, took Rollins' place on the roster in April. He most likely will be moved to make room for Rollins. But because Valdez is out of options, he would need to clear waivers for the Phillies to keep him.
