Aybar has been out since July 21 with a broken toe in his right foot, but Scioscia likes what he's seen from his rehab work recently.
"Erick Aybar ran the cuts, feels good and he'll pick up his workouts," the Angels manager said prior to Friday night's game against the White Sox. "Right now, [returning Monday] is a probability. There's still some things he has to do, but he's moving along great."
As for reliever Scott Downs, who recently went on the DL with a strained left shoulder, the timeline isn't as progressive.
"Scott Downs is still just taking it easy," Scioscia said. "He won't pick up a ball until early next week."
