Another Friday... another lineup shuffle for the Saskatchewan Roughriders.

The Green and White have released import linebacker Tony Taylor.

The team has also added 2 imports and 2 non-imports to the roster.

Linebacker Daren Stone -- originally a 6th round pick of the Atlanta Falcons -- also spent some time with the Baltimore Ravens. The Jamaican-born linebacker also played 8 games last year with the Calgary Stampeders.

The other import -- defensive lineman Mick Williams, joins the team after stints with the Chicago Bears and New York Jets in 2010.

Running back Nathan Riva comes fresh off of four seasons in the C-I-S with the University of Western Mustangs. Last year he carried the ball 92 times for 568 yards and 9 touchdowns.

Wide receiver Bogdan Raic joins the team fresh off his collegiate career with the Ottawa Gee Gees, also in the C-I-S. He made 25 catches for 497 yards last year.

As Canadian, undrafted players, Riva and Raic will not count against the Roughies' 75-man training camp roster.
