Quinn Sullivan out for season with ACL tear

The Philadelphia Union will be without one of its young stars for the final two regular season games and postseason.

Quinn Sullivan confirmed on social media Monday that the injury he picked up on Saturday in Washington D.C. will keep him out for the rest of the season.

“Unfortunately, I tore my ACL this past Saturday,” the 21-year-old Philadelphia native wrote. “I am gutted to not be able to finish this incredible season with the guys. I have full confidence that this special group will lift a trophy. Let’s win it.”

Well… this is a messaged I hoped never to write. Unfortunately, I tore my ACL this past Saturday. I am gutted to not be able to finish this incredible season with the guys. I have full confidence that this special group will lift a trophy. Let’s win it @PhilaUnion . Thank you ❤️ pic.twitter.com/PijKqVUKAP

Sullivan left the match against DC United in the 12th minute with the injury. He has a pair of goals and 9 assists this season, his second full season as a starter. Sullivan also made his full national team debut in May and was a potential candidate for the World Cup squad.
