Josh Johnson, who was scheduled to start against the Yankees on Friday, has been scratched because of tightness in his right triceps.
Instead, the Yankees will face Aaron Laffey, who was let go by the Mets earlier this week and picked up by the Blue Jays.
On the surface, it's a break for the Yanks. Johnson is a big talent, although he is off to a rough start in his first season with Toronto -- 0-1 with a 6.86 ERA in four starts.
That said, Joe Girardi will have to tweak his lineup -- Laffey is a lefty. And the Yankees have had some problems against lefties this season, although they hit three homers and scored five runs off lefty Mark Buehrle on Thursday.
Laffey gave up eight runs in 10 innings of work -- four appearances, two starts -- for the Mets before they decided to cut him loose.
The Yankees are also scheduled to face a lefty on Saturday, J.A. Happ.
