A source says he will make the announcement Tuesday in Ottawa.
The 41-year-old leaves the CFL as a champion after guiding the upstart Redblacks to a dramatic 39-33 overtime win over the Calgary Stampeders in last year’s Grey Cup.
Burris finishes his CFL career with three Grey Cups (1998 and 2008 with Calgary were the others) and two outstanding player awards (2010, 2015). He’s third in all-time passing yards (63,227) and TDs (374).
Burris also spent time in the NFL with Chicago and Green Bay (2001-2002) and is the seventh-leading passer in professional football history with 64,023 yards.
