Lisandro Martinez was carried off the pitch in Manchester United's Europa League quarter-final first leg against Sevilla on Thursday before being stretchered down the tunnel.
The Argentinian went down under no pressure in the 85th minute after turning on the ball, with a number of players surrounding him including United physios and compatriots from the visiting side. He was eventually carried off by Sevilla pair Marcos Acuna and Gonzalo Montiel.
Up on leaving the pitch, Martinez stood on his own and held his hands over his head, looking devastated while staff prepared a stretcher, the Reds defender eventually being taken down the tunnel to huge concern.
