Paris St Germain forward Neymar will be sidelined for four weeks due to a groin injury, the French Ligue 1 club said on Thursday, ruling him out of next week’s Champions League trip for their last-16, first leg against his former club Barcelona.

Neymar made a world record US$269.51 million move to PSG in 2017

Neymar was injured in a challenge during PSG’s 1-0 French Cup win at Ligue 2 side Caen on Wednesday and limped off to be replaced by Kylian Mbappe.

The 29-year-old Brazilian’s availability for the return leg in Paris is also in doubt with the match scheduled for March 10.

Neymar scored three goals and provided four assists in PSG’s run to the Champions League final last season, where they lost to Bayern Munich. He has six goals in the competition this season.

The Brazil international spent four seasons at Barcelona and scored 105 goals before making a world record 222 million euros (US$269.51 million) move to PSG in 2017.
