McCann has been diagnosed with multiple nose fractures but has been cleared to play, Roch Kubatko of MASNSports.com reports.
McCann remarkably stayed in Monday's game against the Blue Jays after being struck in the face by a Yariel Rodriguez pitch. He is undoubtedly very sore and the Orioles would probably prefer to avoid using him, if possible, but he'll be available off the bench Tuesday against Toronto.
