Aaron Connolly has completed a permanent move to Hull City, for undisclosed terms.
The Republic of Ireland international joined us in 2016, going onto make his first team debut in August 2017.
Technical director David Weir said, "Aaron has spent the last few seasons out on loan, but with Hull he settled well.
"He knows Liam Rosenior from their time here together, and Liam is the ideal person to get the best out of Aaron.
"We wish Aaron the very best for the future."
The 23-year-old had a dream start to his league career with us, netting a brace against Tottenham Hotspur in his first full Premier League start.
Aaron went on to make 52 appearances in all competitions for us, scoring eight goals.
