David Murphy, one of Blues’ star performers this season, has had his immediate St Andrew’s future secured.
Blues have activated the two-year option on the left-back’s contract.
Murphy, 28, would have been available on a free transfer this summer had Blues not done so.
Retaining Murphy was always on manager Chris Hughton’s early agenda once Blues Championship campaign ended.
And the news will lift the spirits among those supporters fearful that Blues’ financial plight could hinder Hughton’s squad building.
The club have stated that discussions with Stephen Carr and Colin Doyle, both of whom are out of contract, are ‘ongoing’.
While Jake Jervis has been offered a one-year extension to his contract, which is due to expire this summer.
But Caleb Folan and Cian Hughton, the manager’s son, have both been released at the end of their short-term deals.
The Blues careers of Enric Valles, Ashley Sammons and Luke Hubbins are also over as they have not been offered new terms.
Murphy began the season as back-up to the disaffected Liam Ridgewell.
He came in for Blues early Europa League games and the Carling Cup and performed impressively.
After Ridgewell got injured in November, Murphy got a run in the side and played so well that the position became his by right.
Ridgewell ended up being sold to Albion in January and Murphy went from strength to strength.
Noting himself that this was the fittest and strongest he has felt in his whole career, Murphy was arguably Blues’ most consistent player. And he also found the knack of scoring crucial goals – seven in all.
