You can take Robinson Cancel's mask out of contention for a possible spot on the roster if one of Brian Schneider or Ramon Castro can't go.
Cancel had an MRI on his knee, and will require surgery to repair it, reports Lisa Kennelly on NJ.com.
Pay attention to Gustavo Molina, who has been pretty good when he gets a chance along with Raul Casanova.
Brian Schneider did appear in a minor league game, going 2-4 with a walk, a home run, and double. He said he was good enough to go today, but was held out and will go tomorrow instead.
