20-year-old striker heads back to Weston-Super-Mare on a loan deal until January 9th.
Ash made the switch to Oakwell from the The Seagulls in January 2016 and now rejoins his previous side.
The pacey forward scored a hat-trick for the Reds U21 side during the 2015/16 season away at Leeds United and continued to be involved heavily in the development squad throughout the rest of the season. Brad will now have an opportunity to get some vital first team action at a club he knows well.
We wish Brad all the best in his time at the Woodspring Stadium. Fans can keep up to date on his progress in our weekly loan round-up which will be featured on www.barnsleyfc.co.uk
