In January 2013, it was reported that Lulay signed a two-year contract extension worth a reported $450,000 per season. In Week 12 of the 2013 regular season Lulay suffered an injury to his throwing shoulder when he impacted Alouettes defensive back Geoff Tisdale on a 19-yard rushing touchdown. The touchdown put the Lions up 29–7 with less than 9 minutes in the fourth quarter. The Lions ultimately won the game and opened the season with a record of 7–4. Lulay missed the next six games for the Lions; in that span they went 3–3. He returned to action in the last regular season game of 2013, but he only played for a limited amount of time, attempting only 4 passes, completing 3 of them for 54 yards. The Lions qualified for the playoffs as the 3rd seed in the West Division with a record of 11–7. Lulay started the playoff game against the Roughriders. He completed 20 of 26 pass attempts for 211 yards with no touchdowns or interceptions. He also ran the ball 5 times for 60 yards. Nonetheless, the Lions were defeated by Saskatchewan 29–25, thus ending their 2013 season.
