The Green Brigade have been invited to return to Celtic Park for this evening's UEFA Champions League play-off with Astana.

The self-proclaimed 'ultras' faced a two-game ban from the club after the use of pyrotechnics in the final game of last season against Hearts and then a display of illicit banners in the Champions League qualifier against Linfield.

Celtic were fined by UEFA before instructing those in the Green Brigade section to stay away.

The Green Brigade missed the opening league game of the season against Hearts and the first leg against Rosenborg. The Green Brigade then voluntarily stayed away from the League Cup win over Kilmarnock, but have confirmed they will be back in attendance this evening.

However, the club have stressed that the safe standing section will be monitored to ensure that the safety of everyone within the stadium is guaranteed.

A statement last night read:

"Following the serious safety concerns regarding events at the matches against Hearts in May and Linfield on 19 July, the Club has adopted a Safety Code of Conduct for the Rail Seating Section, which is based on the Club’s risk assessment for the safe operation of that section of the stadium.

"All season ticket holders entering the Rail Seating Section, including those in the Green Brigade Section, must abide by the Rail Seating Section Code of Conduct. In light of the agreement of all season ticket holders entering the rail seating section to abide by the Code, Glasgow City Council Safety Advisory Group has today confirmed that the remaining season ticket holders who had been suspended can return to Celtic Park.

"The safe operation of the rail seating section at Celtic Park requires effective communication and engagement with the supporters in that area. In the last few weeks the Club has engaged with supporters in the Green Brigade section to re-establish the necessary communication and engagement to permit supporters to be readmitted to that section and for it to be operated safely, in consultation with the Safety Advisory Group.

"Safety of all supporters at Celtic Park will always be of paramount importance to the Club. The situation will be monitored by the Club and the Safety Advisory Group on an ongoing basis."
