This is just about the last thing we expected to see from Nolan Patrick on Thursday night.
The 19-year-old Philadelphia Flyers' rookie, a rookie who was the number two pick in the 2017 National Hockey League Entry Draft, showed no fear when things got rough between his Flyers and the Boston Bruins.
Nolan in fact appeared to be the aggressor when he challenged Boston's David Krejci and, after a hard crosscheck from Nolan, Krejci was more than willing to drop the gloves with the young rookie.
The result was a totally unexpected battle between two men who are not known for fighting. Here's the video.
