Sheffield United defender Jack O'Connell has signed a new four-and-a-half-year deal at the club.
The 23-year-old is now contracted at Bramall Lane until the end of the 2021/22 campaign.
The Liverpool-born defender, who joined the Blades from Brentford in the summer of 2016, featured heavily during last season's record-breaking League One title-winning campaign.
O'Connell has made 67 appearances and scored six goals to date, with United currently second in the Sky Bet Championship.
