Young defender Pat Webber has signed his first professional deal with the Blues, a contract which runs to the summer of 2019 with the club having an option for a further season.
Webber, who joined the academy from non-league Worthing in the summer of 2016 after a trial, plays at either left-back or centre-half and made his only senior appearance so far in the Carabao Cup tie at Crystal Palace.
The 18-year-old is the son of Damian Webber, who played for Town boss Mick McCarthy at Millwall.
Yesterday, fellow defender Luke Woolfenden extended his Town contract, also putting pen to paper on a deal which runs to the summer of 2019 with the club having an option for a further year.
