Tennessee Titans coach Mike Munchak says running back Shonn Greene has had arthroscopic surgery on his right knee. Munchak announced Tuesday night on his weekly radio show that Greene had surgery Monday. ''He thought he'd be able to play this week actually so he rehabbed it, he was running but he couldn't quite get over the hump,'' Munchak said. ''So he had it scoped Monday to get it cleaned out. It was what they thought it was. It's something he'll get back rather quickly from.'' Munchak said Greene will be week by week. ''But it's not going to be something that's long term and the good thing is we got it behind us so we should have him refreshed and strong for the rest of the year,'' Munchak said. Greene hurt his knee in the 16-9 opening win at Pittsburgh after four carries for 18 yards. The Titans signed Greene to a three-year contract in March to provide a power complement for Chris Johnson.
