1:56PM: Alain Vigneault said that Kreider felt some swelling in his arm before the game on Wednesday but doctors didn't think it was anything out of the ordinary. After the first period though it got to the point where it "was out of the ordinary so they sent him to the hospital and found out." (NYR)
11:20AM: The Rangers have announced that Chris Kreider has a blood clot in his right arm and will be out "indefinitely."
Brooks adds that it is not yet known if, like Vasilevskiy, Kreider is dealing with Thoracic Outlet Syndrome.
Jed Ortmeyer, currently the Rangers Director of Player Development, had to deal with blood clotting issues during his career.
Adam Rotter: From a hockey point of view this stinks for the Rangers and they lose one of their best top-six forwards and best net-front players. From a non-hockey point of view this is a scary but treatable situation. The hope, from both a hockey and non-hockey point of view, is likely that Kreider has TOS and goes through the same process that Stamkos and Vasilevskiy did. If that is the case and he has to undergo surgery to remove a rib, he might miss the rest of the season but should be fine to continue his career with no issues.
I'd fully expect, unless it's already happened, that Kreider will connect with Stamkos through the many mutual teammates (Dan Girardi, Brian Boyle, Anton Stralman, Ryan Callahan) that the two have had for advice and support. This is a serious situation but both Stamkos and Vasilevskiy seem to have come out of it with no issues (Stamkos has 45 points in 35 games and Vasilevskiy leads the league in wins).
