ALLEN PARK -- The Calvin Johnson saga took another twist Thursday when he reported to Detroit Lions practice.

The megastar didn't play last week with a knee injury and ESPN reported Thursday he "likely" would not practice at all for Sunday's game against the Cleveland Browns. Yet, little more than an hour later, there he was.

Johnson took part in individual drills, including ladders and four-squares, but was otherwise extremely limited. He did not run routes with other receivers during skeleton drills.

Johnson hurt his right knee two weeks ago against the Chicago Bears and had practiced only once since. He missed Sunday's game against the Green Bay Packers.

He has said he was "really close" to playing, but couldn't quite get the knee to cooperate. He seemed to intimate he expected to play Sunday against the Browns.

But ESPN reported Johnson has battled swelling in the knee and wouldn't practice. It also reported that he would be a game-time decision.

Louis Delmas (knee) and Chris Houston (hamstring) also returned to practice after missing Wednesday's session.

RT Jason Fox (knee), TE Tony Scheffler (concussion), RB Theo Riddick (concussion) and Ashlee Palmer skipped practice.
