Johnson signed a 10-day hardship contract with the 76ers on Monday, Adrian Wojnarowski of ESPN reports.
Johnson played in 39 games for the Nets last season, averaging 5.4 points per game on 36.4 percent shooting from beyond the arc. The eighth-year pro will likely step right into a rotational role for Philadelphia, as Tyrese Maxey (quadriceps), Furkan Korkmaz (llness) and Shake Milton (COVID-19 protocols) all may be sidelined for Monday's contest against the Celtics.
