Will Hoskins, released by Albion at the end of last season, has joined Danny Wilson's Barnsley on trial.
The injury-plagued striker is training with the relegated Yorkshiremen and will be offered a deal if he proves his fitness.
Hoskins, 28, has not played a competitive match for 17 months due to knee problems.
Former Albion captain Wilson, who had Hoskins on loan when he was in charge at Sheffield United, told the Barnsley Chronicle: "Will has got real talent and knows where the goal is. We think we can get him fit and, when he is, he can bag you 20 goals a season.
"He had an injury at Brighton and we're more or less sure he's over it. Our staff are making sure he's okay clinically. If he is okay, we'll have a chat and see if we can come to an agreement. He needs to prove himself after the injury but I think he will."
