The "tentative plan" would see Reyes play three games at shortstop and then receive a day off on Sunday before joining Toronto for the start of its next series.
"Hopefully, I think the plan maybe is for him to be back here ready to play on Monday," Blue Jays manager John Gibbons said.
Reyes has been taking ground balls for the past couple of weeks, and his transition back to the field is expected to be a smooth one. The final test before he can be activated from the 15-day disabled list is his ability to hit from the left side.
The 31-year-old hasn't faced pitching in more than three weeks. The brief rehab assignment will ease Reyes into the batter's box and ensure there are no lingering effects from the cracked rib he suffered in Baltimore on the first road trip of the season.
"He's coming off that particular injury, if you throw him into a game here right away, it still bothers him, because adrenaline starts flowing in a game, then you'd have to DL him and start 15 days all over," Gibbons said.
"Down there, if he doesn't feel quite right, comes out, if he just needs a couple of more days, you're still in good shape that way. But, yeah, he needs to see some live pitching."
Reyes is hitting .250 with three extra-base hits, seven RBIs and three stolen bases in 16 games this season.
