Phillies manager Charlie Manuel made the announcement before Thursday's game at Tampa Bay.
Rollins is hitless in his last 19 at-bats. He's hitting .211 with six homers and 27 RBIs in 68 games this season.
Manuel said he wants Rollins to "sit and watch and relax."
Rollins didn't stop to talk with reporters after the Phillies took batting practice Thursday.
"We've got to get him feeling right," Manuel said. "We've got to get Jimmy right. I'll talk with him [Friday] and see where we're at."
Also, the Phillies moved up left-hander Cole Hamels next start from Saturday to Friday at Toronto. The move will give the left-hander one additional start before the All-Star break. J.A. Happ will pitch Saturday against the Blue Jays.
Philadelphia reinstated closer Brad Lidge, who had been out since June 7 with a sprained right knee, from the 15-day disabled list and optioned left-handed reliever Sergio Escalona to Triple-A Lehigh Valley.
