Maarten Stekelenburg will stay in hospital overnight for observation after he was knocked unconscious at San Siro.
The Roma goalkeeper rushed off his line and was accidentally kicked in the right temple by Lucio in the opening minutes of the 0-0 draw.
The Dutch international lost consciousness for around 10 minutes and was stretchered off with a neck brace.
Stekelenburg was taken to the San Carlo hospital in Milan and tests gave him the all-clear.
“There are no problems,” assured director Walter Sabatini. “He had two stitches put in and will stay under observation for tonight, but he's fine.
“He made a brave run off his line and there was a collision, but fortunately nothing happened.
“Maarten will sleep here and return home tomorrow.”
