With the injury to Durant, Kevin Glenn became the starting quarterback, fulfilling the purpose for which he was signed by Saskatchewan. Days later, Chris Milo was released by the Roughriders, and they brought in veteran Paul McCallum as starting kicker. McCallum first game back with the Green and White was on July 5, 2015, a 42–40 overtime loss to the Toronto Argonauts. Weeks later, the Roughriders still didn't have a win in the 2015 season, raising concern on whether head coach Corey Chamblin would eventually be fired. The injury bug around Saskatchewan got worse as quarterback Kevin Glenn, receiver Chris Getzlaf, linebacker Weldon Brown, and receiver Taj Smith were lost to injury. This eventually led to rookie quarterback Brett Smith getting a shot as the starter. During the August 30, 2015 game against the Ottawa Redblacks, head coach Corey Chamblin made the decision to bench Smith in favour of Tino Sunseri following an interception, which disgusted many Roughrider fans. Following another disappointing loss to Ottawa and a record of 0–9 for the first half of the season, head coach Corey Chamblin and general manager Brendan Taman were fired on September 1, 2015. Special teams coordinator Bob Dyce was appointed interim head coach and assistant general manager Jeremy O'Day was appointed interim general manager.
