The Cleveland Cavaliers are this season's most surprising success story, and Ricky Rubio has been a major part of what they've been doing. Unfortunately, the veteran guard went down with a knee injury in the Cavs' 108-104 loss to the New Orleans Pelicans Tuesday night. The team announced Wednesday Rubio will miss the remainder of the season after an MRI confirmed he suffered a torn ACL to his left knee.

Losing Rubio is a major blow to Cleveland, which currently sits as the East's No. 5 seed with the league's fourth-best point differential. 

In the closing minutes of of Cleveland's 108-104 loss to the Pelicans on Tuesday, Rubio appeared to slip, and subsequently his left knee gave out when he planted as he was driving through the paint. 

He went down in clear pain and grabbed at his knee immediately. 

Rubio was helped to the locker room by teammates and was not putting any weight on his knee. He was seen leaving the arena on crutches, per ESPN's Adrian Wojnarowksi, who reported that Rubio will have an MRI on Wednesday. 

Rubio, who was nearing a triple-double with 27 points, 13 rebounds and eight assists when he went down, has been a rock solid presence for the Cavs, particularly next to Darius Garland, who has emerged as a potential All-Star this season. His impact goes beyond his 12-plus points, six-plus assists and four rebounds a night, and I say this as someone who's never really been a Rubio enthusiast.

He's been fantastic for the Cavs, who are such a cool story and fun team to follow right now. Everyone is hoping for the best for Rubio going forward and that he makes a speedy recovery.
