Jesper Jensen stretchered off after Marcus Nilson’s check in Swedish Elite League (VIDEO)

Here's one of those litmus tests for hockey fans: Was Marcus Nilson finishing his check on Rögles defenseman Jesper Jensen, or was this a late hit into the boards well after Jensen released the puck?

The incident occurred in a Swedish Elite League game on Saturday between Rögles and HV7, the home of former AHL scoring hero and beloved NHL journeyman Jason Krog. Jensen's head slammed into the boards near the HV71 bench, and he remained flat on his back until he was finally stretchered off the ice.

He was taken to a hospital and diagnosed with a concussion. The first period was postponed until after the first intermission, when it was completed. HV71 won the game, 3-2, in overtime.

Another look:

Nilson, who played for the Florida Panthers and the Calgary Flames in the NHL, didn't receive a penalty on the play, which is surprising for one reason: politics.

It had been less than a week since HV71 forward Oscar Sundh hit his head on the ice and their game against Lulea was postponed to a later date for completion. Do you think there might have been a penalty in the NHL given that context, and their penchant for overreaction?

As for Jensen, a point of concern: He's two years removed from a devastating concussion suffered when he was 18 years old, and this was his third concussion overall. According to HD.se, Jensen will miss two weeks after the Nilson hit.
