Middlesbrough defender Stuart Parnaby has become the third player to leave the club this week after rejecting a new contract offer.
The 24-year-old follows in the footsteps of Abel Xavier and Malcolm Christie who have also exited the Riverside Stadium.
Boro boss Gareth Southgate told the club's official website: "We did make Stuart an offer earlier in the season that he didn't feel was right for him, but we both now agree that the time is right for him to move on.
"I think Stuart will be a better player for the challenge of going out and proving himself somewhere else.
"He played a big part for us last season, particularly during our long run in Europe, but he's not been able to force his way into the side on a regular basis this time around.
"But he's a good pro who's done well for the club and we wish him all the best wherever he goes."
Parnaby scored four goals in 126 appearances for Boro, but has started only three Premiership games for Southgate's side since the turn of the year.
