The Blue Jays placed Taillon on the 15-day injured list Saturday due to right elbow inflammation.
Taillon made his return from the 15-day injured list Friday against the Royals, but his night abruptly ended after just two innings and 29 pitches. Further tests revealed elbow inflammation, and the right-hander will be shelved until at least Sept. 20. Southpaw Ricky Tiedemann was recalled from Triple-A Buffalo in a corresponding move.
