The Facts: Following up on the ongoing story. ... Friday morning, NFL Media Insider Ian Rapoport reported that Moreno's recent lack of activity is due to his left knee, which has been bothering him this spring. It was sore yesterday, so the Dolphins had him take it easy -- it is not the knee in which he suffered a torn ACL in 2011.

Diehards Line: Rapoport, citing a source who spoke to the player, reported that Moreno's knee did feel better than it had previously; however, arthroscopic surgery is possible. The running back plans to see a doctor in Miami next week to find out. Profootballtalk.com is reporting the same. The South Florida Sun-Sentinel previously reported the knee problem as a vague "medical issue." That medical issue means there is a chance Moreno goes under the knife just weeks before training camp opens. Moreno signed a one-year $3 million contract with the Dolphins this offseason, $1.25 million guaranteed. They could have ended up buying damaged goods if the running back indeed needs surgery prior to the season. And an already skeptical fantasy football community now has more reason to question Moreno's value.
