Fans on social media reacted to the loud boos directed at veteran Corey Perry from the LA Kings fan base before the season opener against the Colorado Avalanche at Crypto.com Arena on Tuesday.Perry joined the Kings earlier this summer after spending two seasons with the Edmonton Oilers.

One tweeted:"Awful look for Kings fans."Jack Weber @Jackweber_LINK@NHLRussell Awful look for Kings fansAnother chimed in:"The stain Edmonton left on the Kings is HUGE and it's showing.
