Phoenix and Denver are set to do battle on Saturday night in an outdoors game for only the second time in NBA history, the Associated Press are reporting.

The first came during the preseason in 1972 when the Suns played the Milwaukee Bucks in a baseball stadium in San Juan, Puerto Rico.

The novelty site for Saturday's game is the Indian Wells Tennis Garden, an NBA-configured arena (minus the roof) that seats 16,000.
