The Pacers fear star guard Victor Oladipo suffered a season-ending knee injury Wednesday against the Raptors, but he'll undergo an MRI exam Thursday to determine the extent of "a serious injury to his right knee," the team announced.

Oladipo was trying to chase down Raptors forward Pascal Siakam and got tangled up with him on the way down.

He immediately signaled for the trainer when he went down and was taken off the court on a stretcher.

The Pacers fear that the knee injury is season-ending and will require surgery to repair, ESPN.com reported, citing unidentified league sources. 

Oladipo entered the game averaging 19.2 points, 5.7 rebounds and 5.3 assists this season. The Pacers went on to win the game, 110-106, to move to 32-15 on the season with a big win over the Eastern Conference leaders. It should've been cause for celebration, but instead Oladipo's injury overshadowed the win. 

If the Pacers are facing the rest of the season without Oladipo, it's a severe blow, losing their leading scorer and team leader. 

"We always want to stick together through thick and thin," Thad Young said after the game ( via IndyStar.com ). "We know with Vic going down it was definitely going to be tough but we want to keep fighting for him."
