Overton was designated for assignment by the Blue Jays on Friday.
Overton was recalled by the Blue Jays on Aug. 27, but he didn't make any appearances during his week in the majors. The right-hander has allowed four hits and two walks while striking out four in 6.2 scoreless innings in the big leagues this year, but he'll be removed from the 40-man roster as part of a move after left-hander Kirby Snead was recalled Friday.
