The Hamilton Tiger-Cats will turn to Dan LeFevour behind centre when they play host to the Ottawa Redblacks on Saturday.
Ti-Cats head coach Kent Austin announced the decision on Thursday, calling LeFevour a genuine "dual-threat."
In two games with the Tiger-Cats this season, 27-year-old has completed 17 passes on 22 attempts for 146 yards. He has thrown no touchdowns and one interception. On the ground, LeFevour has rushed 15 times for 45 yards and one touchdown.
LeFevour is filling in for injured starter Zach Collaros, who suffered a head injury against the Edmonton Eskimos on July 4.
The Tiger-Cats will also be without linebacker Simoni Lawrence, who has a leg injury.
Wide receiver Greg Ellingson's status is unknown with a stomach bug. Austin said Ellingson is one of multiple Ti-Cats who have the flu.
"Hopefully it doesn't get worse," Austin told members of the media on Thursday.
