Mavericks reserve Devean George will have arthroscopic knee surgery, which will probably end his season.

George suffered cartilage damage in his right knee during Wednesday's game against Portland.

"They told me I'm done [for the year]," George said. "But I believe in miracles. The first step is to get it taken care of and go from there."

The injury comes at a bad time for George, who will be an unrestricted free agent this summer.
