Boston's contingency plan with Allen Webster last night didn't work out either--trying to find someone who could pitch better than Felix Doubront(who has been as bad or worse than Romero, but can't be sent to AAA), and it failed miserably. He's not ready.. but Boston has few options.
As for the Jays, it'll likely be Ramon Ortiz, Claudio Vargas, Ryan Tepera, Sean Nolin or Chad Jenkins likely going into the rotation..
