Adrian Peterson says he is still working his way back toward feeling normal after left knee surgery.

The Vikings star running back spoke to reporters Wednesday about his progress during minicamp, providing his familiar optimism on an afternoon otherwise dominated by wide receiver Percy Harvin's request for a trade.

Peterson says Harvin told him recently that he's cutting so well on his surgically repaired left knee it's hard to tell he was injured. But Peterson adds he knows his body is ''just not there yet'' at full recovery.

He's on track for training camp, but how much he can do and whether the team will let him play at the start of the regular season has yet to be determined.
