Andre Roberson Stretchered off vs. Pistons After Suffering Knee Injury

Oklahoma City Thunder shooting guard Andre Roberson appeared to suffer a serious leg injury during Saturday's road game against the Detroit Pistons at Little Caesars Arena.

Royce Young of ESPN.com noted Roberson's leg was wrapped before a stretcher was used to take him off the court. 

Head coach Billy Donovan confirmed it's a patellar tendon injury, but the extent is unknown, per Young.

Adrian Wojnarowski of ESPN reported "preliminary" testing showed a possible ruptured patellar tendon.

Here's a look at the play that caused the injury during the third quarter:

Roberson Wiped Out Badley on the Floor

While it's hard to identify exactly where the guard got hurt, Erik Horne‏ of the Oklahoman pointed out his left knee seemed to buckle as he slipped.

Roberson is averaging 5.0 points, 4.7 rebounds and 1.2 steals while shooting 53.1 percent from the field across 38 appearances for OKC this season.

The 26-year-old University of Colorado product is best known for his defensive contributions. He ranks third in the NBA in Defensive Real Plus-Minus, per ESPN.com.

Alex Abrines will likely step into the Thunder's starting lineup for as long as Roberson remains sidelined. It should also lead to extra opportunities for Terrance Ferguson and Raymond Felton as part of the team's backcourt rotation.
