Bristol City manager Keith Millen has confirmed goalkeeper Stephen Henderson will be leaving the club after failing to agree a new contract.
It is thought the 23-year-old is now in talks about a possible move to Championship rivals Portsmouth.
Millen told the club website: "From 1 July, Stephen was free to talk to other clubs and choose to join another team.
"He didn't return to training and he didn't accept our contract offer so now we will see what club he joins."
Last week, Millen stated he was hoping to keep the Republic of Ireland Under-21 international, who spent last season out on loan at Yeovil Town.
"It's a shame he's decided to leave and I'm disappointed because I really wanted to keep him," added Millen.
"With the quality we have at the club, he clearly sees his first-team chances limited and equally it's very difficult keeping three goalkeepers happy."
If a deal is confirmed, Bristol City would be due compensation as Henderson is under the age of 24.
