The NHL and its players reportedly plan to broach the possibility of banning meldonium in the offseason.

"The National Hockey League and NHLPA are expected to sit down in the summer and address the issue of meldonium and whether it goes on to the banned substances list," TSN's Bob McKenzie reported on Thursday's edition of "Insider Trading."

More than half of the players in Russia's Under-18 evaluation camp reportedly tested positive for the drug, which Maria Sharapova was recently penalized for taking.

Meldonium isn't on the NHL's list of banned substances because the World Anti-Doping Agency only added it to theirs on Jan. 1.

Players participating in the upcoming World Championship can be tested for meldonium, while testing at the World Cup of Hockey will be done by the NHL and NHLPA, so that will depend on what the two sides determine in the summer, according to McKenzie.

Russia will reportedly send its Under-17 team to the Under-18 tournament as a result of the positive tests.
