Joe Gyau has confirmed that he will need a second surgery on his injured left knee. The United States midfielder, who has been out for three months, will miss the remainder of the season, according to Ruhr Nachrichten.

Gyau was originally injured while playing for the U.S. in a friendly on October 10. At the time, he was diagnosed with a torn meniscus and underwent surgery. The expectation was that he would return in January and he looked on track for that when he came off the bench three times for Borussia Dortmund II late in 2014, but then he strained a muscle in his left leg and his full return was pushed back to February.

The 22-year-old certainly won't be back in February now, and there are questions about whether he will ever be back with Dortmund. The club signed him to a one-year contract last summer and by the time Gyau is healthy again, he will be out of contract. The American did show flashes, scoring two goals in 11 matches for the BVB reserves and even getting into a match with the first team, but there is no word on whether they plan on signing him to a new contract in light of the latest injury news.

Gyau is still young and he showed flashes of his potential in the fall, for both the U.S. and BVB reserves, but this a big blow. His club future is in doubt, which means his national team future is also in doubt. He'll have a tough road back, and that assumes he can get back to 100 percent. Hopefully he can.
