The Pittsburgh Penguins are looking to do something only four other teams in NHL history have accomplished, come back from a 3-0 deficit to win a playoff series. To do so, the Penguins will need to win Sunday in Game 6 at Philadelphia to force a deciding Game 7 in Pittsburgh on Tuesday.

In other Sunday game action, the Washington Capitals are just one win away from advancing to the semifinal round of the 2012 Eastern Conference Playoffs and out West, the No. 8 seed is trying to down the No. 1 seed in convincing fashion.

Here is the complete schedule for NHL Playoff games to be played on Sunday:

Penguins Vs. Flyers: 12:00 p.m. ET, NBC

Bruins Vs. Capitals: 3:00 p.m. ET, NBC

Kings Vs. Canucks: 8:00 p.m. ET, NBC Sports Network
