Mendis was fielding under the helmet at short leg when Dilruwan Perera delivered a full toss to Jake Doran who pulled it hard straight into Mendis on Day one of the visitors' sole tour match against the Cricket Australia XI in Hobart.
The Sri Lankan had ducked his head to take cover, putting his hands in front of his helmet, and the ball struck him flush on the hand.
Mendis was in immediate discomfort as teammates rushed to his aid. Footage showed the pinkie finger on his right hand pointing at an unnatural angle and he was in obvious discomfort while being treated by medical staff from both teams as he left the field.
Two balls after Mendis had left the field Dilruwan dropped short and Doran swept, clipping Roshen on the left hand.
He was moved out of the position for the final ball of that over with Kurtis Patterson on strike, but found himself back at short-leg for the first ball of the next over with Doran taking guard.
That ball was again smashed in short-leg's direction, and Roshen took another nasty hit to his left forearm on the bounce, which saw him throw down his helmet in disgust and grimace in pain.
