The Oklahoma City Thunder certainly missed the services of Paul George in Friday's loss to the Milwaukee Bucks.

According to the team's game notes, both George and Andre Roberson are currently listed as out for Sunday's game against the Dallas Mavericks. The Thunder cancelled Saturday's practice due to icy roads.

George missed Friday's game due to soreness in his left knee. It could be a game-time decision for Sunday's tip-off against the Mavericks, but it's too early to tell. With the Thunder not having practice, it's unclear how much he would've taken part in.

Roberson is also dealing with a knee injury as he has patellar tendinitis. He did play against the Bucks and registered 5 points and 9 rebounds in 35 minutes.

Sunday's tip is obviously a long way off and game notes aren't the final decision regarding injuries most of the time. However, it appears that the Thunder are going to make sure that George is close to being 100 percent. Oklahoma City will be looking to rebound from their first defeat in the last seven games.
