Paris - Neymar will travel to Qatar to undergo a "complete assessment" six weeks into his recovery from a fractured right foot, the club said on Thursday.

The Brazil forward watched on forlornly from the stands at the Parc des Princes as PSG crashed out of the Champions League last 16 on Wednesday to Manchester United on away goals following a 3-1 defeat.

"Neymar Jr will travel to Aspetar (sports clinic) in Qatar for the next 3 days as scheduled in the initial recovery plan," the club wrote on its Twitter account.

"He will undertake a complete assessment after six weeks of his injury. He will be accompanied by a medical team from PSG."

The 27-year-old damaged the fifth metatarsal in his right foot in a French Cup win over Strasbourg on January 23 and was ruled out for 10 weeks.

PSG were hoping he would be healed enough to get back on the pitch in time for a potential Champions League quarter-final in April, but the French side suffered a humiliating exit as United sensationally overturned a 2-0 first-leg deficit.
