On December 13th, news came out that shook up the entire NHL community. That news being that Philadelphia Flyers Oskar Lindblom had been diagnosed with Ewing's sarcoma, a rare form of cancer that occurs in the bones or in the soft tissue around the bones.

Since the news came out, several teams throughout the NHL have worn t-shirts supporting the Flyers forward in a gesture that has been labelled #OskarStrong. Today, the Pittsburgh Penguins put aside a rivalry to show support for the 23-year-old Lindblom. The Penguins Twitter account posted two photos of players wearing the Oskar Strong shirts. The first picture from left to right shows Evgeni Malkin, Sidney Crosby, and Kris Letang. The other photo they posted from left to right is Patric Hornqvist and Marcus Pettersson.

It is a very classy move by the Penguins, and truly shows just how much respect NHL players have for one another. Although these two teams have one of the biggest rivalries in the NHL, they were able to separate the sport from real life and support Lindblom through his tough times.

There haven't been any recent updates on Lindblom's condition, but it was announced shortly after he was diagnosed that he would miss the remainder of the season. Lindblom was having what looked to be a breakout season for the Flyers, as he had registered 11 goals and seven assists in 30 games.
