Matt Cain was scratched from his scheduled Tuesday start after cutting his right index finger while making a sandwich in the Giants clubhouse hours before the first pitch, but for now at least the team is planning on him rejoining the rotation Monday.

Yusmeiro Petit filled in at the last minute Tuesday and will again be on call next week in case Cain can’t pitch. Petit tossed six shutout innings in his place against the Padres and has a 3.31 ERA in 73 total innings for the Giants dating back to 2012. In the meantime Cain is avoiding doing any throwing for fear that the wound will open up again.
