Of course, this isn't your typical player. When it comes to Megatron, standard operating procedures might not apply.
On Saturday, ProFootballWeekly.com's Eric Edholm cited a source in reporting that Johnson is a true gametime decision for Sunday's Week 9 matchup against the Jacksonville Jaguars. If he does play, he could be limited to third-down situations.
Johnson is listed as questionable on Detroit's injury report. The knee issue is the latest in a collection of nagging injuries that have hindered Johnson's production this season. He has one touchdown catch this season after setting a franchise record with 16 scores last season. Johnson has just six catches for 80 yards over the Lions' last two games.
We don't envy the dilemma facing Johnson fantasy owners.
