VANCOUVER — The BC Lions have tweaked their football operations department days ahead of the National Combine, announcing Tuesday the additions of Canadian Football Hall of Famer Bob O’Billovich and former CFL offensive coordinator Bill Diedrick.

The team also announced that Geroy Simon has been named the club’s director of CIS scouting and player personnel assistant.

Both Neil McEvoy, the team’s director of football operations and player personnel, as well as Ryan Rigmaiden, the Lions’ director of U.S. scouting will continue to serve in their current capacities.

“Bob and Bill bring a vast amount of CFL experience and knowledge to their roles and they understand the kind of players who are best suited for our game, while Geroy’s work will be invaluable to our success,” said VP of football operations, GM and Head Coach Wally Buono.

“Adding more expertise to our player personnel department well help us in both the short and long term and I’m looking forward to seeing our organization benefit from their contributions.”

Today’s announcement marks a return to the club for O’Billovich, who was the Lions’ Director of Player Personnel under Buono from 2003 to 2007 before joining the Hamilton Tiger-Cats as GM in 2008. Also serving as Lions head coach for 43 games from 1990-1992, O’Billovich will scout CIS players in Ontario and Quebec and attend eastern-based NFL training camps.

The veteran coach began his CFL days with the Edmonton Eskimos in 1991 before moving onto NCAA postings at Washington, Stanford and Notre Dame.

Simon, the CFL’s all-time leader in receiving yards and receptions, will now focus his energy specifically on the evaluation of Canadian football talent in advance of this year’s CFL Draft which is slated for Tuesday, May 10, as well as during the CIS regular season.

The Lions have also added Michael Lionello to the coaching staff, who will be in charge of quality control. Lionello joins the club after serving at Simon Fraser in a number of areas including director of football operations, recruiting coordinator, running backs coach and video coordinator.
