The lawyer in Derek Boogaard's family's wrongful death lawsuit against the NHL has asked to delay a court ruling on the case, citing new evidence that could prove vital to the accusation that the league did not do enough prevent Boogaard's ultimately fatal addiction to painkillers.

Boogaard, a former enforcer for the Minnesota Wild and New York Rangers, died in May of 2011 of an accidental drug overdose. He was home on an unsupervised leave from a rehab program at the time of his death. Boogaard was 28 years old.

According to TSN, the Boogaard family's lawyer, Bill Gibbs, sent a letter to the court asking to delay a ruling on the lawsuit while he works to get evidence unsealed from a separate case, a lawsuit filed by over 80 former players against the NHL claiming the league does not do enough to protect players from the harmful long-term effects of concussions. Gibbs is also a lawyer in the concussion case.
