Arrighetti (foot) could be activated from the 15-day injured list to start Friday's game against the Yankees, Arden Zwelling of Sportsnet.ca reports.
Arrighetti threw 3.2 innings and 50 pitches in a rehab start with Triple-A Buffalo on Sunday, so if he does come back Friday he would be facing workload limitations. The right-hander is dealing with Morton's neuroma in his right foot, and the expectation is that he will have to pitch through some discomfort down the stretch for the Blue Jays.
