David Phelps hit A.J. Pierzynski with a pitch in the eighth inning of New York's 3-2 win over Boston on Sunday night, and the ball deflected off McCann's right index finger. McCann stayed in the game.
Catcher Francisco Cervelli, playing at first base because of injuries to others, left in the fourth inning after getting hurt running to first. While originally called out, Cervelli was ruled safe after a video review - giving New York its third run of the game.
Cervelli had an MRI that showed a grade 2 right hamstring strain, and New York said he will be put on the disabled list before Tuesday's game against the Chicago Cubs, a move that will be retroactive to Monday.
Pitcher Shane Greene was optioned to Triple-A Scranton/Wilkes-Barre after Sunday's game.
