Ipswich Town defender Luke Woolfenden has signed a new three-year contract.
The 23-year-old, who is a product of the League One club's academy, has made 107 first-team appearances, with 38 of them coming this season.
"I was really enjoying my football in the second half of the season and I am delighted to have signed a new contract," he said.
Town have also taken up an option to extend the contract of midfielder Sone Aluko, 33, by a year.
Aluko, who has seven caps for Nigeria, has made 36 appearances and scored three goals since joining from Derby County last August.
Meanwhile, three youngsters have been given new deals.
Forward Tommy Hughes, 21, has signed for six months, while midfielder Tawanda Chirewa, 18, and striker Tyreece Simpson, 20, have been given one-year contracts.
Earlier this week, forward Kayden Jackson and wing-back Wes Burns also agreed new terms at Portman Road.
