The 26-year-old former Den Bosch and Millwall striker scored, but Mogga wants more time to asses him.
The Hibs boss said:
"He hasn't done any pre-season training, he doesn't have any energy levels and that's why we only played him for a short time last night.
"It's not really fair to judge a player when he is not fit, so Berry will spend a week with us getting himself fit and we will make some decisions after that. I am not going to make any snap decisions on players."
