Paris Saint-Germain will be sweating over the fitness of Neymar after the Brazilian star was forced to leave Wednesday's Champions League match against Istanbul Basaksehir with an undisclosed injury.

The 28-year-old pulled up early in the first half after a long run, appearing to favor his groin. He tried to play on, even having his left leg strapped by the medical staff before returning to the pitch, but was ultimately removed in the 26th minute, heading straight down the tunnel after being substituted.

Pablo Sarabia was brought on in his place.

Though the French side has strength in depth, PSG manager Thomas Tuchel has been hamstrung throughout the young season by a combination of injuries to key players and a COVID-19 outbreak within the squad.

Neymar himself missed time earlier in the campaign after testing positive in September.

PSG went into Wednesday's contest in Turkey needing a victory after they opened their Group H adventure with a loss to Manchester United on Matchday 1.
