Tucker has been ruled out for Tuesday's game against the Pacers due to left lower leg inflammation, Tim Reynolds of the Associated Press reports.
Tucker sustained the injury in Sunday's loss to the Pistons, and while the Heat haven't indicated how long he'll be sidelined, the veteran forward will be forced to miss at least one game. KZ Okpala is the leading candidate to step in as the Heat's starting power forward, and he could shoulder heavy minutes with all of Tucker, Jimmy Butler (tailbone), Markieff Morris (neck) and Bam Adebayo (thumb) sidelined.
