Atlanta Hawks forward Chandler Parsons was involved in a car accident following Wednesday's practice and has been diagnosed with a concussion and whiplash, according to Chris Haynes of Yahoo Sports.

Parsons has played in just five games this season, averaging 2.8 points over 10.8 minutes per game.

There was a time when Parsons was one of the top up-and-coming two-way wings in the NBA, but knee injuries have absolutely derailed his career.

Chandler Parsons, who played his collegiate basketball at the University of Florida, was originally selected by the Houston Rockets in the second round (38th pick overall) of the 2011 NBA Draft.

He played in 63 games and made 57 starts during his lockout-shortened rookie campaign, registering 9.5 points, 4.8 rebounds, 2.1 assists and 1.2 steals across 28.6 minutes a night while shooting 45.2 percent from the floor, 33.7 percent from three-point range and 55.1 percent from the free-throw line.

The 31-year-old then showed considerable progression during his sophomore season, recording 15.5 points, 5.3 boards, 3.5 assists and one steal through 36.3 minutes per game while making 48.6 percent of his field-goal attempts, 38.5 percent of his long-distance tries and 74.2 percent of his foul shots.

After a similar season in 2013-14, Parsons landed a lucrative two-year deal with the Dallas Mavericks during the summer of 2014, which was when the knee issues began.

He played in 66 and 61 games, respectively, in his two seasons with the Mavericks before landing a four-year, $94 million deal with the Memphis Grizzlies.

The contract turned out to be a disaster, as Parsons appeared in just 34, 26 and 25 contests in three seasons with the Grizzlies before being traded to the Hawks this past summer.
