Tallet hasn't pitched in the Majors since suffering an intercostal strain in his rib-cage area on July 3. The veteran reliever had his flight to Toronto delayed on Monday, but arrived just before Toronto's series finale against the Rays.
The 33-year-old lefty has yet to pitch for the Blue Jays this season. He was acquired along with Colby Rasmus in a multiplayer deal on July 27 and immediately began rehabbing the injury at the club's Minor League Complex in Dunedin, Fla.
Tallet made four appearances for Class A Dunedin and allowed one run in four innings. He also surrendered four hits and struck out five without issuing a walk.
The Oklahoma native previously spent five seasons in Toronto. He is 16-24 with a 4.76 ERA in 241 career appearances.
Toronto opened a spot on its 25-man active roster on Sunday when left-handed reliever Wil Ledezma was designated for assignment.
