After almost two weeks of speculation, FC Dallas confirmed on Wednesday that Young Designated Player Mauro Díaz is scheduled to undergo a surgical procedure on his right knee on May 13 and is expected to return in 6-10 weeks.
Díaz left the April 26 FC Dallas game against D.C. United shortly before halftime and did not play in Sunday's 1-0 loss to the New York Red Bulls. FC Dallas officials had termed the injury "day-to-day" while waiting on reports from team doctors.
The 23-year-old Argentine joined Dallas last summer and already had three goals and three assists in eight games this season, earning Etihad Airways MLS Player of the Month honors for March 2014.
FC Dallas had started the season 5-1-1 with a +8 goal differential before Díaz's injury. They have since been outscored 5-0 in 136 minutes without Díaz but have played 126 of those 136 minutes short-handed due to ejections.
A 10-week recovery would place Díaz on course for a return in late July or early August, meaning he will likely miss at least 10 games due to the injury. In his absence, Homegrown player Danny Garcia started in an attacking midfield spot on Sunday.
Dallas are also expected to play without teenage defender Kellyn Acosta for at least six weeks due to a left knee injury and have been short-handed recently after being assessed three red cards in two games.
