Golden Knights captain Mark Stone is considered week to week with an upper-body injury, coach Bruce Cassidy said Friday.

Stone left the Knights’ 4-2 win against the Florida Panthers in the first period Thursday and did not return. He missed 45 games last season with a back injury that required surgery in May. Cassidy, when asked if Stone reinjured his back, only labeled the injury as upper body.

Stone is the Knights’ second-leading scorer with 38 points in 43 games. He will miss his first game of the season Saturday against the Edmonton Oilers at T-Mobile Arena.
