FC Dallas opens play in the Lamar Hunt U.S. Open Cup on Tuesday night at FC Dallas Stadium against the Charlotte Eagles of USL Pro. However, FCD will be at less than full strength, which has been the norm all season.

Midfielder Brek Shea, who just finished serving a three-game suspension in league play after kicking a ball at an official, has been ruled out for the game as he continues to be bothered by turf toe. The Bryan native did not train on Monday morning, first riding a stationary bike and then doing some work with an exercise band before leaving the field with his left foot in a boot.

“Still banged up a little bit,” Dallas coach Schellas Hyndman said when asked about Shea’s condition. “I think what happens when you have something like a turf toe, a normal thing to do is you try to play through the pain. And when you try to do that, because you’re protecting it, you start to alienate something else so maybe a different part of his foot now is becoming an issue. Yeah, he won’t play tomorrow night.”

Fellow midfielder Daniel Hernandez also won’t play on Tuesday but for a different reason. The former FCD captain earned a red card in Dallas’ lost at Seattle in the 2011 USOC semifinals and won’t be available for selection.

“He’s gone through three games in eight days. He’s not playing tomorrow because of the red card he got in Seattle,” Hyndman said.

Central attacking midfielder Ricardo Villar will also not play as he continues to recover from a foot injury suffered back in April. However, Tuesday may or may not mark the return of Fabian Castillo, the speedy Colombian who has missed the last few games with an ankle issue.

Castillo did go through training on Monday morning on the stadium field but did so with his left ankle wrapped. “We’ll make a decision whether we’re going to start him or have him off the bench but he’s probably about 85 percent,” Hyndman said.
