Isaiah Thomas has entered the NBA's health and safety protocols one day after joining the Dallas Mavericks. 

Thomas replaced Brandon Knight, who was also on a hardship until he entered the league's protocols. 

Thomas was previously on a 10-day deal with the Los Angeles Lakers. 

The Mavericks called Thomas on Wednesday morning as he was grocery shopping near his home in Seattle. Thomas booked a flight to Sacramento and arrived a few hours before tipoff.
