11:31pm: Joe Girardi told reporters McCann will be re-evaluated tomorrow, which will determine if he needs to be placed on the disabled list.
10:18pm: McCann has been diagnosed with a mild concussion, though there really is no such thing as a mild brain injury. It’s unclear if he will be placed on the 7-day concussion disabled list.
9:49pm: Brian McCann left tonight’s game for an unknown reason in the sixth inning. He took a hard foul tip to the face mask earlier in the game, but did stay in for another few innings. I supposed the Yankees could be playing it safe with him after taking a big lead. They do have catching depth in the minors, but losing McCann for any length of time would be pretty bad. Stay tuned for updates.
