Houston Mayor Sylvester Turner has declared Thursday “Go Rockets Day,” encouraging city employees and Houstonians to wear their Rockets gear.

The mayor tweeted, “Go @HoustonRockets! I'm declaring tomorrow "Go Rockets Day" at the City of Houston. Employees can wear Rockets gear #RunAsOne”

The declaration comes ahead of Houston’s Game 6 against the San Antonio Spurs Thursday in the second round of the NBA Playoffs. The Rockets must win Thursday to force a Game 7 or their season will be over.
