Blues forward Sone Aluko has signed a new one-year deal, his previous contract having been up at the end of the season.
Aluko was offered the new terms in May along with Massimo Luongo, who put pen to paper last week.
The 34-year-old made only four League One starts during 2022/23, a knee injury in August having hampered his campaign, although manager Kieran McKenna spoke about the role the forward played in the dressing room on a number of occasions during the season.
"It’s good to get done and I’m happy to extend my time at the club,” Aluko told the club site.
"The conversations started with the manager maybe at the end of the season before [2021/22] about what we might do at this point, and obviously to now be staying after promotion is even sweeter.
"The manager has been fantastic since he came in. The on-pitch stuff speaks for itself but he is also a really good person. We get on really well and see the game in the same way.
"Everyone here has been really good to me and this is a fantastic place to be.”
McKenna added: "Sone is so important to the environment and the culture here day-to-day. He’s highly regarded by his teammates, first and foremost, but also the staff around the club.
"Sone has shown his quality on the pitch but, of course, had a big injury last season. He’s shown what he can do and the FA Cup games last season instantly come to mind.
"He shows his quality on the training pitches day-to-day but perhaps more importantly is his influence on the group and our younger players.
"I think he will have a very bright future in football in other aspects once he finishes as a player, so we’re delighted he is going to be around the group next season.”
The former Nigerian international joined Town in the summer of 2021 having left Reading at the end of the previous season and having had a spell on trial with Derby.
