BC head to Calgary in their best form of the season so far, having won back-to-back games to improve to 3-5.
The Lions opened the campaign with back-to-back road games at fell 31-27 at Saskatchewan and 41-27 in Hamilton.
They then dropped the home opener to Calgary, 41-33, before finally getting off the mark in early July as they took down Edmonton, 36-24.
BC failed to build on that as they were beaten 19-17 in Edmonton and 26-12 at home by Toronto, but they have rallied in recent weeks.
The Lions got back to winning ways with a 35-17 success in Winnipeg, and backed that up last Saturday as they returned home to down Hamilton, 27-24.
