Rangers forward Chris Kreider underwent successful rib resection surgery on Sunday, the team announced on Tuesday afternoon.
Kreider, who has been out with a blood clot in his right arm, will be reevaluated in six weeks and remains out indefinitely. A rib resection is a surgical procedure used to treat thoracic outlet syndrome, a compression of blood vessels and/or nerves between the collarbone and the first rib.
Kreider left the Dec. 27 game against the Capitals after the first period with a swollen arm and was sent to the Hospital for Special Surgery, where the blood clot was discovered.
