Celtic trained at Lennoxtown on Tuesday morning before flying out to Trondheim for their Champions League qualifier with Rosenborg.
Striker Leigh Griffiths is expected to be fit for the match in Norway as Brendan Rodgers' men bid to book a place in Friday's draw for the play-offs.
It finished 0-0 when the sides met at Celtic Park last Wednesday and Rodgers told the club website: “I said before the game to the players that it wouldn’t be won on last week, there is still another half to play in Rosenborg.
“We anticipated the two games would be tough in their own right so we expect exactly the same again but if we play our game we can score the goals we need to qualify.”
