VANCOUVER — Veteran B.C. Lions quarterback Travis Lulay has been sidelined with another injury.

The 34-year-old left the Lions' matchup with the Ottawa Redblacks at the end of the second quarter Friday after he was sandwiched in between hits from Ottawa's Rico Murray and J.R. Taval.

The Lions said on Twitter that Lulay was undergoing concussion protocol and "doubtful to return." Jonathan Jennings replaced Lulay to start the second half.

Now in his 10th season with the Lions, Lulay went into the game having thrown 1,696 yards, seven touchdowns and four interceptions in six games this season.

He missed the first game of the season while rehabbing a knee injury suffered last season, then dressed as Jennings' back up for the next two matches before re-claiming his starting spot in mid-July.

Jennings threw for 487 yards, two touchdowns and three interceptions in B.C.'s first three games of the year.

The Lions are 3-6 for the year and are struggling to stay in the race for a playoff position.

B.C. was up 10-1 over Ottawa going into the second half.
