Celtics' Josh Richardson, Hornets' Cody Martin enter protocols

Celtics swingman Josh Richardson and Hornets swingman Cody Martin have entered the NBA’s health and safety protocols, the teams announced (Twitter links).

Richardson, 26, exited the league’s protocols just under a week ago. Boston now has seven players in protocols ahead of Monday’s game against Philadelphia, plus Jayson Tatum (left ankle sprain), Romeo Langford (neck pain) and Dennis Schroder (illness) on the injury report as questionable.

Martin, also 26, will enter protocols for the first time this season. His brother, Caleb, is going through the same situation with the Heat, although it’s unclear if this is related to Cody’s addition.

For his part, Richardson has provided two-way production for Boston, averaging 10.7 points in 25.2 minutes per game this season. Martin has done much of the same for Charlotte, though the third-year player is shooting a scorching 51% from three-point range.

Richardson and Martin are part of a growing list of players who are in the NBA’s protocols. More than a dozen players were placed on Sunday, while five game postponements were announced.
