Laurent Robinson will not play and has no fantasy value, Blackmon time?

Laurent Robinson (concussion) didn't practice all week and he has been ruled out for Sunday's game against the Bears.

Analysis: This is the third time he had concussion symptoms in the last three months and there was almost no doubt that Robinson was going to sit this one out. Chances are he could miss additional games, too. Justin Blackmon hasn't really put it together yet, but the Jaguars are going to have to use a short passing game to move the ball against a viscous pass rush and ball-hawking DBs. Blackmon might be a useful flex this week and Robinson can be left on the waiver wire in almost any format.
