Sixers' run of injuries continues as Josh Richardson suffers concussion by bonking heads with teammate

Another game, another starter lost for the Philadelphia 76ers.

The Sixers’ run of awful luck started last week when Ben Simmons went down indefinitely with a nerve impingement in his lower back, and continued when Joel Embiid was ruled out for at least a week with a left shoulder sprain.

Now, the team has lost a third start in Josh Richardson, who exited Sunday’s game with a concussion, according to USA Today’s Mark Medina.

Richardson sustained the injury after his head collided with the head of teammate Alec Burks.

Richardson will now enter the concussion protocol, and it’s unknown when he’ll be back.

Keeps getting worse for Sixers

With Richardson missing for most of the game and without Simmons and Embiid, the Sixers fell 136-130 to the Los Angeles Clippers on Sunday. Shake Milton started in Simmons’ place and dropped a career-high 39 points on 14-of-20 shooting (7-of-9 from 3-point range), but it still wasn’t enough.

Richardson was acquired last summer in the sign-and-trade that landed Jimmy Butler with the Miami Heat, and has averaged 14.0 points, 3.5 rebounds and 3.2 assists in his first season with the Sixers. He has also missed small chunks of November, December, January and February with hamstring injuries.

After Sunday’s loss, the Sixers remain in fifth place in the Eastern Conference at 37-24. That’s well short of the team’s preseason expectations, and not likely to get better as long some of its key players out.
