Russell Westbrook has made significant progress in his recovery from a second surgery on his knee and could return to the Oklahoma City Thunder's lineup within two weeks, according to sources.

The Thunder issued an original timetable of six to eight weeks from Wednesday's opening night for Westbrook, but barring an unforeseen setback he could be back in the lineup by mid-November.

Westbrook has impressed the Thunder with his explosion and return to form.

After rehabilitating a torn meniscus suffered in the Western Conference playoffs in April, Westbrook spent the summer rehabilitating the injury until a loose stitch forced a second surgical procedure in early October.
