Injury news keeps piling up for the Dynamo.
Midfielder Juan David Cabezas has been ruled out of Saturday's game against the New York Red Bulls due a concussion he suffered in training.
Cabezas appeared in Houston's second and third games, earning his first start two weeks ago at Portland.
News of Cabezas' concussion became official 15 minutes after the club revealed forward Romell Quioto will miss two to four weeks with a dislocated shoulder he suffered while playing for Honduras in a World Cup Qualifer last week.
Centerback Agus also is out for a few weeks after reaggravating a left hamstring injury in training last week.
