U.S. international Quinn Sullivan confirmed that he sustained an ACL injury during the Philadelphia Union’s 6-0 victory over D.C. United on the weekend. The 21-year-old midfielder lasted just 12 minutes before the knee injury. He initially attempted to play on, but it soon became apparent that would not be possible.
When injury occurred
Sullivan was involved in a challenge with Joao Peglow during the Union’s MLS clash with DC, leading to him eventually being replaced in the 13th minute. He was clearly in some pain, with a knee problem causing him discomfort. Medical tests revealed ligament damage.
He is set to be sidelined for several months, with his 2025 campaign being brought to an abrupt halt.

On social media, Sullivan posted, “Well… this is a message 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, but really proud to be a part of this team. I have full confidence that this special group will lift a trophy. Let’s win it @philaunion. Thank you all.”
The Union are very much in contention for Supporters’ Shield honors in 2025, sitting top of the Eastern Conference, and victory in their final two regular season games could see them fend off the likes of FC Cincinnati and Inter Miami – who saw Lionel Messi and Co make history last season when landing that title.
Impressive record earned new contract
Sullivan has played an integral role for Philly this term, with a standout campaign. On the back of registering five goals and 11 assists last year, he had found the target on two occasions while teeing up nine efforts through 28 appearances. That contribution helped to earn the homegrown star a new contract in October 2024.
Sporting director Ernst Tanner said of those terms: “Quinn had a breakout season this year, showing how high his potential can be. As one of only two players to appear in every regular season match, his growing importance to the club is clear. He stepped up with versatility and maturity this season, playing wherever he was needed. We’re happy to have come to an agreement to keep him with the Union for the coming years.”
GettyWorld Cup dream on hold
Sullivan has also become a senior international, with his exploits being noted by manager Mauricio Pochettino in the USMNT camp. A first call-up was earned over the summer of 2025, allowing a debut to be made in a friendly loss to Turkey.
His dreams of gracing the World Cup finals next summer appear to be hanging by a thread, with it difficult to see how he could force his way into contention.
The long-term future remains bright, though, and there will be more opportunities – including further World Cups – in which a decisive contribution on the grandest of stages can be made.
