Neymar took a whack to the face, but played on and grabbed his second goal as Paris Saint-Germain won at Nice 3-0 in Ligue 1 on Saturday.
The Brazil forward was caught by Wylan Cyprien's flailing arm as they contested the ball near the hour mark of an otherwise one-sided contest.
Cyprien was sent off for a second yellow card, and Neymar sat down for a while and had a little blood wiped from his mouth with a sponge. He got up and carried on, playing on for several minutes as he ran around with the makeshift plaster device protruding from his mouth.
Neymar had already done damage of his own to Nice, expertly curling PSG in front midway through the first half from the edge of the penalty area. The ball fizzed past goalkeeper Walter Benitez before he could react and lodged in the bottom right corner.
That was enough for league leaders PSG's eighth-straight win.
France star Kylian Mbappe returned from a three-game ban and was desperate to score for PSG, but too much so. He fluffed a good chance right at the start of the second half by taking too many touches. After his shot was blocked near the line, attacking midfielder Christopher Nkunku stroked in the rebound to make it 2-0.
PSG have struggled in the past at Nice, who always reserve a vitriolic welcome, but should have scored several more. When Neymar eventually got the third goal, it was in the second minute of injury time as Mbappe set him up for an easy tap-in.
With seven goals, Neymar is one ahead of Marseille winger Florian Thauvin at the top of the league scoring chart.
