Kings edge Flyers in OT
Richards returned to Philadelphia for the first time since his shocking trade in June.
Richards was the Flyers captain and led them to the Stanley Cup finals in 2010.
He heard mostly cheers during his pregame introduction and a huge ovation when the Flyers thanked him on the big screen for his years of service.
The goodwill ended soon after and he was booed each time he touched the puck.
Richards raised his arms in celebration after Johnson redirected his shot past Ilya Bryzgalov to spoil Philadelphia's perfect start.
Flyers forward James van Riemsdyk was whistled for tripping in the final moments of regulation, leading to the power-play attempt for Los Angeles at the start of overtime.
It was a furious end to the third that allowed Richards to star again at the Wells Fargo Center.
Williams scored on a rebound off his own backhand to beat Bryzgalov with 7:25 left in the third for his second goal of the game and a 2-1 lead.
Richards was a helpless spectator in the penalty box after he was whistled for hooking. The Flyers pounced and Matt Carle scored the tying goal when he fired one from the circle past Quick not long after.
More Flyers fans than usual, many wearing a Richards Flyers jersey, pressed along the gate outside the arena waiting for his arrival. Some fans asked each other if they thought Richards would be booed. He wasn't, at least, not at first.
Richards received loud cheers amid a smattering of boos when he was introduced as the starting center.
He received a rousing ovation in the first period when the Flyers flashed a message on the videoboard that read: ''Thank you, Mike Richards, for all your contributions and service to the Flyers organization and our fans.''
Richards deserved the warm welcome from the 19,644 fans after his solid career in the orange and black.
Richards spent the past three seasons as team captain. He scored 133 goals and had 349 points in 453 games since making his debut with the Flyers in 2005.
He had no desire to leave and was ''shocked'' when he learned of the deal.
Richards needed time to regroup and couldn't fully come to terms with the trade until he made his first visit to Los Angeles.
He was a perfect fit with Flyers West. Former teammate Simon Gagne is on the team. John Stevens, his former head coach in Philadelphia, is now an assistant. Terry Murray was an assistant under Stevens and is now the Kings head coach. Kings assistant general manager Ron Hextall was inducted into the Flyers Hall of Fame in 2008 and is one of the greatest goalies in team history.
Kings forward Dustin Penner came to the aid of his teammate and started a fight with Rinaldo only 24 seconds into the game.
Doughty returned for a shift but was not on the bench in the second period. The Kings later ruled him out of the game with the injury and said he will miss seven to 10 days.
The Kings are ready to head home after a whirlwind start of the season.
They opened in Europe for an exhibition and played their first two regular-season games in Stockholm and Berlin before playing two games on the East Coast on the way back to California.
The Kings play their home opener Tuesday.
After the excitement of the Penner-Rinaldo fight, the Flyers gave their fans more reason to roar when Danny Briere scored his first goal of the season moments after the Kings killed a 5-on-3 power play. Jaromir Jagr's perfect pass across the crease found Briere in front of the net for the open look.
Williams tied it midway though the period with an assist from Gagne.
Notes: The Flyers play seven home games in October, then a combined eight in November and December. ... This was the only game of the season between the Kings and Flyers. ... The Flyers failed to go 4-0 for the first time since 1995-96.
