I blew my knee out a long time ago, so maybe the medical science has advanced, but if they actually repaired his meniscus, I have a hard time seeing him back this season. A true repair usually has a much longer recovery because the meniscus has limited blood supply.
If they just trimmed the tear, a return this season is possible, but I’d still expect at least a month.
But given that he’s a young, prized pitcher, I’d expect the Jays to be extra cautious with him. Good chance he's done for the year IMO.
