Weston McKennie is set to miss a significant chunk of Schalke’s impending relegation battle after the 20-year-old midfielder badly rolled his ankle during the U.S. men’s national team’s victory over Ecuador on Thursday, the Bundesliga club revealed on Friday.

McKennie was forced off in the 68th minute, not long after he went up for an aerial challenge and landed on the outside of his left foot, causing to the ankle to violently roll over.

From Schalke’s official statement:

“The U.S. (men’s) national team confirmed to Schalke that he hasn’t broken anything, but it looks like he has bruised the bone and damaged a ligament. He will soon see a foot specialist in the U.S. to determine the exact nature of the injury.”

While Schalke didn’t provide an estimated timeframe for McKennie’s return, Tottenham Hotspur and England forward Harry Kane has suffered a series of ankle injuries quite similar to that of McKennie over the past two or three seasons. Kane has generally been out of action for 6-10 weeks, with an additional 2-4 weeks of live action typically required to regain his full form and fitness. For USMNT purposes, the 2019 CONCACAF Gold Cup kicks off on June 15, 12 weeks from today.

Schalke currently sit 15th in the Bundesliga, three points and one spot clear of the relegation playoff spot, with eight games left to play.
