Collins said he was confident Rice would be ready to go when the Mets return home on Friday to face the Phillies.
"With [Thursday] being [an off-day], it gives him an extra day to quiet that down a little bit," Collins said.
The Mets had also been avoiding right-hander Carlos Torres, who was nursing a similar back issue earlier this week. Torres, the Mets' primary eighth-inning setup man, returned in the eighth inning Wednesday, ultimately taking the loss.
