The Calgary Stampeders re-signed quarterbacks Drew Tate and Bo Levi Mitchell to contract extensions Tuesday.

"Drew and Bo are both very talented quarterbacks who have enjoyed great success as members of the Stampeders," Calgary coach/GM John Hufnagel said in a statement. "They work extremely well together and their decision to sign extensions with the Stampeders gives us great long-term stability at what is obviously a key position."

Tate has been with Calgary since '09. He became the starter late in the '11 season but injuries have limited him to eight regular-season and two playoff starts since then.

The 29-year-old has completed 259 of 381 passes for 3,270 yards and 24 touchdowns with just nine interceptions.

Mitchell, 23, has been with Calgary the past two seasons but was 3-0 as a starter last year. He completed 94 of 135 passes for 1,156 yards with 10 TDs and three interceptions.
