"Just a little tiny bit of inflammation, and that's it. All good news," said Johnson to reporters on Saturday afternoon. He will play catch on Sunday and Monday before any plans for his return to the rotation are finalized.
Johnson, 29, is 0-1 with a 6.86 ERA in four starts for Toronto this year. The Blue Jays acquired him from the Marlins this past offseason as part of the 12-player blockbuster trade. They're stuck in the AL East cellar at 9-15 going into Saturday's play.
Johnson has a history of arm trouble, specifically Tommy John surgery and shoulder inflammation. This is the first time that he has had a problem with his triceps as a big leaguer.
Left-hander Aaron Laffey started in place of Johnson on Friday and allowed two runs on five walks and two hits in 2 2/3 innings against the Yankees.
