Play-making linebacker Marcus Ball will be back for the Eastern Final.
The 30-year-old has been activated from the six-game injured list, per sources.
He was hurt in the Argonauts Week 15 win against Hamilton. Ball played in 14 regular season games making 57 tackles, recording two interceptions and forcing one fumble.
The versatile defender has been a large part of the Argos turnaround on defence with a number of new faces and defensive coordinator Corey Chamblin coordinating it all. Ball returned to Toronto in 2017 after two productive seasons in 2012 and 2013 with the Argos earned him NFL opportunities.
