The Game One loss for the San Jose Sharks and Justin Braun paled compared to the news that the defenseman's father-in-law Tom Lysiak, a former NHL All-Star died of leukemia on Monday.

The former Atlanta Flames great was 63.

Lysiak was selected second overall -- behind the New York Islanders' Denis Potivin -- in the 1973 NHL Draft.

He finished second in the Rookie-of-the-Year voting -- behind Potvin, again.

Overall, Lysiak played 13 season in the NHL, notching 292 goals and 551 points.

He was a three-time All-Star for the Atlanta Flames and led them in scoring five times.

Lysiak moved from Atlanta to Chicago in an eight-player deal during the 1978-79 season.

Lysiak's time in Chicago was marred by an incident in a game on Oct. 30, 1983.

He was tossed from the faceoff circle on more than one occasion in the game. One final time he was asked to leave and Lysiak took his stick and struck linesman Ron Foyt behind the knee, sending him to the ice.

The punishment? A 20-game suspension for a player who was almost exclusively know for his skill and talent and in no way rough play.
