When will Derrick Rose finally return to the court? Who knows? Yeah, he has been cleared to play, but Rose doesn't believe he will be ready until he's able to dunk confidently off of his left foot. But that may not be the only thing standing in his way.

According to ESPN Chicago, D-Rose is now facing some hamstring problems. These issues may have to do with the fact that the 24-year-old point guard has been "taking full contact in practice for well over a month" and as a result, "his hamstrings are 'on fire' after those workouts."

While these issues probably won't cause too much of a setback in Rose's rehab, it should be noted that D-Rose has been sitting recently for this reason. And let's not forget that Rose has already stated that he won't return until he's 100% and if these hamstring problems linger, the start of the 2013-14 NBA season may start looking like the best option.
