Nash suffered the injury in the second quarter of the team’s 116-106 loss to the Trail Blazers in Portland.
Nash did not practice Thursday and was seen walking with a limp.
“Luckily, it’s not anything major or structural. It’s just a contusion in a bad area,” Nash said. “Maybe I’m too optimistic to say doubtful, but it’s definitely touch and go.”
Steve Blake , who subbed for Nash on Wednesday, would start in Nash’s place if the new Laker can’t play.
