Toronto has yet to officially announce a corresponding roster move but the expectation is that Cecil will be activated from the paternity list prior to Friday night's game against the Rangers. Cecil missed the three-game series in San Francisco to attend the birth of his daughter Braelynn.
Cecil is 0-5 with a 5.59 ERA in 15 appearances this season. Tepera has allowed three earned runs in 2 1/3 innings for the Blue Jays.
