Philadelphia Union goalkeeper Zac MacMath will not play in Saturday's game at FC Dallas (8:30 p.m., The Comcast Network) due to a flareup of concussion symptoms.
MacMath did not travel with the team to Dallas, according to a spokesperson for the Union.
He suffered the concussion when he took a knee to the head in the May 8 game at Seattle.
MacMath was listed as "out" on the Major League Soccer injury report published Tuesday of last week, which made it likely that he would not play against the New York Red Bulls this past Sunday. But he was upgraded to "probable" in the Friday injury report two days before kickoff.
As I watched Sunday's game, I did not notice anything especially discernable regarding signs of concussion after-effects. But it certainly is not unusual for after-effects to flare up at a later point, whether someone is cleared to play or not.
Taylor Twellman, the ESPN color analyst who helped launch a foundation to research sports-related concussions, reported on Twitter that it "looks like [MacMath] took a hit in training this week."
Twellman noted earlier that it "is a HUGE part that the player is open about how he feels not ALL on team/doctors/etc It has to be BOTH ways."
MacMath's absence means that either Chase Harrison or Chris Konopka will start Saturday night. Since MacMath has played every minute of every league game this season, I do not know who is more like to start. So don't bother asking.
(Sorry, but I had to. I know you would have asked and I honestly don't know the answer.)
At least the Union won't be the only shorthanded team in the game. As I noted Thursday, FC Dallas could be without many of its regular starters, including goalkeeper Kevin Hartman.
Here are the full injury reports for both teams as of Friday evening:
Out: GK Zac MacMath (concussion symptoms); M Roger Torres (left knee surgery recovery); F Krystian Witkowski (concussion)
Doubtful: D Chris Albright (left big toe sprain)
Questionable: D Gabriel Farfan (right knee contusion)
