FC Dallas midfielder Mauro Diaz will miss the remainder of the season after having surgery to repair a torn Achilles tendon on Wednesday, the club has announced.

Diaz went down in the 89th minute of Dallas' 2-1 defeat of the Seattle Sounders on Sunday. He will miss the remaining two regular season fixtures as well as the entire playoffs should the club advance to the MLS Cup Final.

The 25-year-old Argentine leads the team with 10 assists this season while contributing an additional five goals to the cause.

Diaz joined FC Dallas from Argentine giants River Plate in the summer of 2013. He has scored 22 goals and provided 32 assists in 92 appearances for the club overall.
