The Denver Nuggets suffered a heartbreaking loss to the Dallas Mavericks on Tuesday, as Peyton Watson’s buzzer-beating game-winner attempt came just inches away from dropping. However, the most crushing part of Tuesday’s loss was not the missed game-winner; it was an injury to starting forward Cam Johnson.

Johnson left Tuesday’s contest a few minutes into the fourth quarter after going down with a knee injury, and on Wednesday, the Nuggets learned the severity of the injury.

ESPN’s Shams Charania reports, “Cam Johnson has been diagnosed with a bone bruise in his right knee and is expected to miss some time, sources tell ESPN. Best case scenario as an MRI reveals no structural damage or major injury after a serious land on his leg in Dallas.”
