The Houston Dynamo trained indoors at the Houston Texans' Methodist Training Center on Wednesday. The team ran through a fitness session in the morning and ballwork - including soccer tennis! - in the afternoon. The Dynamo are likely to use the bubble again on Friday. A photo gallery from the training session is currently available, and videos from the unique day will be available on Thursday.
