United States midfielder Stuart Holden will be out six months with a knee injury following a horrific tackle suffered this weekend during an Englih Premier League game with Bolton Wanderers, the team announced.

“First and foremost our main concern is for Stuart and his recovery. He will get all the time and support that he needs,” Bolton Manager Owen Coyle said in the release. “Stuart has been outstanding for me this season and he has shown in his performances that he is one of the best midfielders in the Barclays Premier League. He has such desire, strength of character and a winning mentality, and he will draw on all those attributes in his rehabilitation.”

Holden had been called into U.S. camp for friendlies against Argentina and Paraguay later this month but was taken off the roster. The injury will also hold him out of the CONCACAF Gold Cup this summer, an unfortunate turn for a player who figured to play a prominent role after a strong club season in England.

Holden suffered a gash that received 26 stitches following a studs-up tackle by Manchester United’s Jonny Evans on Saturday. Evans was red carded for the tackle.

Initial X-rays showed no broken bones, however there was clearly more significant damage. Holden tweeted from his account, @stuholden, that he will be undergoing surgery later Monday.

“I can promise you all I will come back stronger and better than before. Have had bad luck in the past and will continue to beat it. #bwfc” Holden tweeted.

Holden also wrote on his account that he received a phone call from Evans and that it was “just unfortunate part of the game.”

Holden also was ruled out for six weeks after suffering a fractured fibula following a reckless tackle by Nigel de Jong in a friendly match against the Netherlands last March.
