Injury updates: Boss, White, Carrasco, Sanyang

However, coach Sigi Schmid clarified this week that the club has shut down Boss for the remainder of the season, regardless of competitions, due to his recent run of concussions.

"I was devastated," Boss said of learning the club's decision. "Obviously I want to play. It's been hard not to play, but at the same time it's kind of out of my control. I couldn't make that decision. I didn't waste my time worrying about the things I can't control. I understand where the doctors are coming from, and I appreciate their caution in the issue. But it's hard not to play, obviously."

Boss is back training with the club however.

"I'm happy to be back out on the field," Boss said today. "I'm kind of taking it slow, but no more concussion symptoms, so that's positive. It feels good to be back on the field. I feel sharp. I feel good. Just keep working and get ready for next year."

Meanwhile, coach Sigi Schmid gave a few other medical updates: forward O'Brian White is doing better and increasing his treadmill work after a vein transplant to deal with a blood clot in his leg; midfielder Servando Carrasco "suffered a setback" and is day-to-day; while midfielder Amadou Sanyanghas “a little bit of a strange injury” from which he is making slow progress.
