Denver Nuggets forward Will Barton has left the NBA campus to rehab his right knee offsite.

Barton’s ongoing knee issues have led to soreness in other parts of his body and he will seek a second opinion for his discomfort, according to Mike Singer of The Denver Post.

Barton played in a scrimmage on July 27, but he did not appear in any of the eight “seeding games” or Game 1 of the playoffs.

The original diagnosis for Barton was right knee soreness, but there’s clearly more going on.

Barton’s knee has not improved and he is reportedly frustrated that it hasn’t gotten better.

Rookie Michael Porter Jr. will continue to provide a scoring boost for the Nuggets in Barton’s absence.
