“Andre Wisdom has been the victim of an unprovoked assault and robbery,” mentioned an announcement from Derby.
“He sustained injuries which resulted in him being admitted to hospital, where he is in a stable condition.
“Merseyside Police are investigating and the membership will focus its efforts on supporting Andre and his household.”
Merseyside Police did not immediately respond to CNN Sport’s request for comment.
Wisdom performed in Derby’s 2-1 victory in opposition to Reading on Saturday.
He signed for the membership from Liverpool after a sequence of mortgage spells and has made 20 appearances thus far this season.
Derby has an outdoor likelihood of constructing the Championship playoffs because the membership seeks promotion to the English Premier League.
