Orlando Magic forward Aaron Gordon couldn't hold back his tears after witnessing his teammate Jonathan Isaac suffer what appears to be a serious knee injury on Sunday.

Isaac crashed hard to the floor in the fourth quarter of the Magic's match against the Sacramento Kings following a strong drive to the basket. He immediately grimaced in pain while clutching his knee before eventually being wheeled off off the floor with a wheelchair.

Gordon described how devastating it was to see his frontcourt mate go out like that, per Josh Robbins of The Athletic.

Jonathan Isaac has already overcome a lot just to be able to play inside the NBA's restart at Disney World in Orlando, Florida. He was expected to miss the rest of the season after hyperextending his knee last January, but he willed himself back to game shape to help the Magic secure a playoff berth.

While Aaron Gordon and the rest of the team are still awaiting his MRI results, there's already a crippling notion that Isaac might have torn his ACL.

After struggling in his first two seasons in the pros, the 22-year-old Florida State product has come into his own in his third year. Isaac averaged career-highs of 12.1 points and 6.9 rebounds in 32 games. He was also quite the menace on the defensive end, registering impressive tallies of 2.4 blocks and 1.5 steals per game.

Isaac also stole headlines last week after becoming the first NBA player to stand during the national anthem. Miami Heat center Meyers Leonard and San Antonio Spurs head coach Gregg Popovich have since followed suit.

The Magic forward's rather controversial move has earned him a lot of admirers, as his jersey sales skyrocketed shortly after his decision to not kneel.
