The Philadelphia 76ers are getting thinner and thinner. As if it wasn't already enough that Joel Embiid was out with a sore knee, it looks like fellow big man Boban Marjanovic may be joining him on the sidelines, as he injured his knee in the Sixers' win over the New Orleans Pelicans on Monday night and will undergo further testing on Tuesday, according to Serena Winters of NBC Sports Philly.

Philadelphia acquired Marjanovic in a deadline deal with the L.A. Clippers, a package that was headlined by Tobias Harris.

However, with the Sixers incredibly thin in their frontcourt, Marjanovic had actually been a valuable asset to the team since arriving, and on Monday night, for example, he posted 12 points, 10 rebounds and a couple of blocks.

Unfortunately, the 30-year-old was in such pain after injuring his right knee against the Pelicans that he had to be carried off the court.

On the season, Marjanovic is averaging 7.1 points and 4.6 rebounds over 11.5 minutes per game while shooting 62.9 percent from the floor and 74.3 percent from the free-throw line.

The Serbian came over to the NBA for the 2015-16 campaign after signing with the San Antonio Spurs. That season, he played in 54 games, registering 5.5 points and 3.6 boards across 9.4 minutes a night while making 60.3 percent of his field-goal attempts and 76.3 percent of his foul shots.

He then proceeded to sign with the Detroit Pistons, where he spent a season-and-a-half before being dealt to the Clippers in a deal that sent Blake Griffin to the Pistons.

Marjanovic owns career averages of six points and 3.9 rebounds per game.
