Danner (forearm) was optioned to minor-league camp by the Blue Jays on Monday, Keegan Matheson of MLB.com reports.
Danner was a longshot to make the roster anyway, but the inflammation in his right forearm made it all but a guarantee that he'd open the year in the minors. The 2017 second-round pick could be a bullpen option for the Jays at some point over the summer once healthy.
