shooting guard will not play Saturday against the Detroit Pistons due to neck spasms, per the Associated Press' Tim Reynolds.
The 20-year-old has averaged 17.6 points on 46.9 percent shooting (30.2 percent from three-point range) alongside 6.7 rebounds in 33.7 minutes per game.
Herro helped guide the Heat to a much-improved 44-29 record last season after the team finished 39-43 the year prior. Miami cruised into the playoffs thanks in part to his efforts, which included 12 games of 20 or more points (and a high of 29).
Herro dominated in the playoffs en route to helping Miami reach the NBA Finals, where the Heat fell to the Los Angeles Lakers.
