Josh Richardson's Celtics debut will have to wait


Josh Richardson's debut for the Boston Celtics will have to wait. 

The team announced that Richardson, acquired from the Dallas Mavericks this offseason, will miss the first game of Boston's 75th season due to a migraine.

The 28-year-old Richardson, who has also played for the Miami Heat and Philadelphia 76ers since entering the NBA in 2015 as a second-round draft choice out of Tennessee, is a projected rotational piece for the Celtics who can play either shooting guard or small forward.

In six NBA seasons, the 6-foot-5 Richardson has averaged 12.3 points per game, including 12.1 last season in 59 games for the Mavericks. He's a career 35.8% shooter from 3-point range. 

Following Wednesday's opener on the road against the New York Knicks, Richardson's first game in green could come when the Celtics will play their home opener Friday against the Toronto Raptors.
