Paris Saint-Germain striker Kylian Mbappe left the field on a stretcher after an accidental clash with Lyon goalkeeper Anthony Lopes.
Marco Verratti's raking pass sent the France international through on Lopes' goal in the first half of a top-of-the-table clash in Ligue 1 on Sunday.
But Lopes got to the ball a split-second before Mbappe, subsequently crashing into the 19-year-old, who had already required treatment for a head wound. Mbappe had to be replaced by Julian Draxler following a lengthy delay.
