The Hoops have been training on astroturf in preparation for Wednesday’s third round Champions League second leg against the Swedes and the midfielder hopes they have the different variety of surface covered as they look to build on their 1-0 lead.
"It's going to be hard, it's on astroturf. We have been training on astroturf for a few days trying to get our heads around it,” said Brown.
"We won't know what kind it is until we get there. But we are not worried.
"We have had a lot of games on it in the last few seasons and are getting quite used to it."
Of the first leg in Glasgow, Brown added: "Elfsborg came out with a game plan at Celtic Park and they stuck to it.
"They tried to defend and sneak a goal at the end hoping to get a draw so they could take us back to the astro-pitch. We did well on the night, though, and even though they were 16 games into their season we looked a lot fitter than them.
"We've not really had a long break so match fitness has caught up quite quickly. The lads look sharp in training as well as the games."
