Caleb Martin has become a key rotation player for the Miami Heat, despite being on a Two-Way contract. Prior to Saturday's game against the Chicago Bulls, Martin had played in 23 of Miami's first 25 games, including two starts.

Now, Martin has joined a seemingly ever-increasing list of players in the NBA's health and safety protocols.

Heat coach Erik Spoelstra said he didn't have a lot of information, as the team was informed shortly before their win over the Bulls that Martin would be out. If Martin tested positive, he'll miss a minimum of 10 days, or until he can return two negative tests 24-hours apart.

Martin joins the injured Bam Adebayo, Jimmy Butler, Markieff Morris and Victor Oladipo as players who are out for the Heat.

Martin's status as a Two-Way player means he is only eligible to be active for up to 50 games for Miami. As his role has increased, that game-limit has become an increasing concern. The Heat do have an open roster, but have been prioritizing flexibility under the hard cap.
