Ticat Roster Moves- Aug 31/06

According the the cfl.ca transactions page, the Ticats moved Iain Fleming, Lawrence Gordon and Arnold Parker from the active roster to the non-active roster today. They have also added non-import offensive lineman Carl Gourgues to the non-active roster.

yeah, but what does it really mean??

I'm ass-uming non-roster means they can't play ?
