Both players required surgery, and they will be sidelined for several months.

“Dear JDub & Cason, we are all behind you. Get well soon. Love, OKC,” the sign said.

Midtown Mutts is a dog park that is located in the former site of the food truck park Bleu Garten.

The Thunder, short-handed due to injuries, are 4-1 this season, falling to the Dallas Mavericks Wednesday without Wallace, Williams, Alex Caruso, Chet Holmgren, Nikola Topic and Thomas Sorber.

Oklahoma City will face the Rockets at 7:30 p.m. Saturday.

Background on J-Dub and Caso’s injuries
