Scary moment at the end of Tuesday’s Caps-Kings game as Caps defenseman  Jack Hillen collided with Alex Ovechkin during overtime. Hitting one another at full speed while crossing center ice, Hillen’s head ran into Ovechkin’s chest. Hillen laid motionless on the ice, apparently knocked out.

Hillen eventually regained consciousness and was helped off the ice to the applause of a relieved Verizon Center crowd, but his injury is yet another chapter in the very sad book of Hillen’s tenure in Washington.

As you can see, Hillen and Ovechkin did not see one another until it was too late. Ovechkin was in full stride, and Hillen was turning towards the bench.

Ovechkin was knocked backwards, appearing to have the wind knocked out of him. Hillen’s head bounced backwards, and he fell to the ice.

Ovechkin returned to action a few moments later, seemingly unscathed.

Hillen was not so lucky. He did not return for the scant remainder of overtime. If Hillen misses time, it would mark the third time he’s been hurt as a Capital. He first suffered a shoulder injury in the 2012-13 season opener. Then in October, Hillen hurt his knee after a hit by Lance Bouma, requiring knee reconstruction before returning earlier this month.

Hillen had been hurt by Ovechkin before, taking a slapshot puck to his jaw in 2010.

Hillen has played just 26 games since signing with the Caps. He has three goals and seven assists in that time.

Here’s hoping this latest injury is short-lived. Get well soon, Jack.
