Barnsley have terminated the contracts of defender Scott Wiseman and striker Chris Dagnall by mutual consent.
Wiseman, 28, has made 25 appearances for the struggling Reds this season, but does not feature in new boss Danny Wilson's plans and has joined League One club Preston.
Wilson said: "We wish him all the best and it's the way things work out in football, we just needed to freshen things up."
Dagnall is also leaving Oakwell, bringing to an end a disappointing two-year stay in South Yorkshire where he scored just 11 goals.
The 27-year-old spent time on loan at Coventry earlier this season before being brought back by Wilson to be assessed.
