Arencibia, who hasn't played since fracturing his right hand on July 26, made his first rehab appearance for Class A Dunedin on Sunday. He went 1-for-5 with a double and a walk in six plate appearances at designated hitter.
The 26-year-old will continue his rehab in Florida and could return to the Blue Jays on Friday in Boston, or at the conclusion of that upcoming three-game series.
"Talked to him before [batting practice] yesterday, after BP and then after the game, he felt good physically," Blue Jays manager John Farrell told reporters on Monday morning.
"Today's the last day of the regular season, there's typically a day off before playoffs begin. I don't have their playoff schedule, but he could return to us Friday in Boston or it could be when we return from Boston. Both of those are realistic time-frames."
Arencibia is hitting .242 with 16 homers and 50 RBIs in 81 games this season. He has yet to appear behind the plate in the Minors and likely will need at least a couple of starts at catcher before getting the green light to return.
"I was just reviewing his progression, he will catch while in Dunedin in the next day or two," Farrell said. "Most importantly, we're trying to get his timing back at the plate first. He's been catching bullpens. He's been receiving volume work off the pitching machine. Just trying to get his legs back in game shape as quick as possible."
Veterans Jeff Mathis and Yorvit Torrealba have been filling in during Arencibia's absence. It's possible that a fourth catcher -- utilityman Yan Gomes -- also will be added to the Blue Jays' roster when Triple-A Las Vegas' season comes to an end on Monday.
