Los Angeles Lakers forward Pau Gasol sustained a tear of the plantar fascia in his right foot and will be out at least six weeks, media reports said.
The injury was confirmed by an MRI that the Spaniard underwent in Boston on Wednesday, CBS Sports reported.
Gasol could undergo rehabilitation and possibly be back in action in six to eight weeks, CBS Sports said.
The other option for the Spaniard is surgery, which would sideline him for between 10 and 12 weeks but provide a higher likelihood of a complete recovery.
Gasol is expected to get a second opinion in the next few days, the sports network said.
The Spaniard will fly to Los Angeles on Thursday and be examined by the Lakers' team doctor, the Los Angeles Times reported.
Gasol was injured in Tuesday night's 92-83 win against the Brooklyn Nets.
The forward was hurt as he defended against Nets center Brook Lopez with four minutes left in the game.
Gasol planted his right foot and then went down.
Trainers treated Gasol and he tried to continue playing, but he quickly called for a substitute due to the severe pain.
He left the arena on crutches. EFE
