NHL clears Blues, Golden Knights after multiple false positives
The players who tested positive were isolated earlier Wednesday while further testing was conducted. Those results all came back negative.
The league says it investigated the initial tests because the "reported results emanated from the same laboratory," in addition to "other peculiarities and similarities among the test results themselves."
Since the follow-up tests were negative, the NHL says every affected player "will be eligible to play in their team's next game."
St. Louis is scheduled to play Game 2 of its first-round series against the Colorado Avalanche on Wednesday night at 10:30 p.m. EST. The Golden Knights will face the Minnesota Wild in Game 3 of their series Thursday.
