Sophie Cunningham suffered a brutal injury during the Indiana Fever's 99-93 overtime win against the Connecticut Sun on Sunday. The Fever guard’s sister, Lindsey Cunningham, was furious after watching her sibling grimace in pain while clutching her right knee.Lindsey didn’t mince words as she launched a no-holds-barred attack on the WNBA’s officiating standards. She even urged the league to shift its focus from fining players for speaking their minds to improving the quality of officiating by making new hires."@WNBA maybe you should focus less on fining players for commenting on your poor officiating & more about hiring officials that are able to call a consistent game and protect your athletes. Pathetic. Praying for you @sophaller," she tweeted.Lindsey Cunningham @LbreezzyyLINK.@WNBA maybe you should focus less on fining players for commenting on your poor officiating & more about hiring officials that are able to call a consistent game and protect your athletes.
