Celtic ultras have been spotted marching towards Parkhead and lighting pyro ahead of the match against Livingston.
Fans were seeing wearing balaclavas and fireworks were also left off.
The fixture marks the first time the Green Brigade will be back in the stadium since October after the group and the club ended their feud.
You can watch footage of the march in the video below.
Yaaassssss!!! Green Brigade return for today's Celtic - Livingston game. Let's hope they can inspire the team to a convincing victory as Martindale will no doubt have Livy fired-up to give his first-love clubs (Rangers v1.0 & v2.0) an early Xmas present. pic.twitter.com/aElW7qpkMv
