After learning that he had been diagnosed with a left knee sprain, Cavs rookie Kevin Porter Jr. decided to send out a tweet to his fans for their support.

Porter went down in obvious pain during the third quarter of the Cavs’ Sunday game against the Timberwolves. While dribbling around a screen at the top of the key, Wolves forward Robert Covington stepped on Porter’s foot as he was trying to make a move in the opposite direction.

Porter grabbed his knee in pain. His teammates rushed over, but the damage had already been done. Cavs trainer Steve Spiro later helped the talented rookie to the locker room. He logged 19 minutes, scoring six points and five rebounds.

Cavs fans were concerned about Porter’s status overnight, as they were awaiting the results of an MRI. Around noon on Monday, the team officially announced that he had suffered a left knee sprain, noting that he will be re-evaluated in two weeks time.

Porter has been a bright light in a dim season for the Cavs. The 19-year-old has made 34 appearances thus far (two starts), racking up averages of 8.5 points on 43.9 percent shooting from the field (29.7 percent from beyond the arc), 3.3 rebounds, 1.9 assists and just under one steal (0.9) in 21.8 minutes per game.

The Cavs are high on Porter’s potential, so they’ll likely take a cautious approach to his return. In the meantime, players like Dante Exum, Brandon Knight and Cedi Osman will see upticks in their usage rates.
