Jerome Thomas and Gonzalo Jara have been released by West Brom, who are in negotiations with a further four players.
Thomas and Jara did not feature often for Steve Clarke’s side in the Premier League this season, and have both left the club after their contracts came close to expiring.
The 30-year-old Thomas made 10 Premier League appearances for West Brom in 2012-13 but enjoyed a successful six-match loan spell at Championship side Leeds United, in which he scored one goal.
Defender Jara featured just once for West Brom in the league, and spent around three months on loan to Nottingham Forest, who also play in the Championship.
The Chilean international featured 16 times for Forest, making 14 starts, and is now looking for a new home.
“Both Jerome and Gonzalo have played important roles in helping the club reach and stay in the Premier League since joining us four years ago,” West Brom’s sporting and technical director Richard Garlick said.
“They have found first-team opportunities harder to come by this season and had spells out on loan. They both leave with our best wishes.”
Defender Steven Reid and midfielder Zoltan Gera did not make enough appearances this season to trigger automatic one-year extensions on their contracts, but the pair are both negotiating with West Brom.
The loan spell of Macedonian Goran Popov has ended, but West Brom were impressed, and are speaking to Dynamo Kyiv about the possibility of signing the 28-year-old permanently.
Striker Marc-Antoine Fortune has also seen his deal run down, but his representatives are in talks with the club about a possible extension.
