The former Kingstonian forward signed from Dulwich Hamlet in the close season, but things haven’t worked out on his return to the Beveree.
He is the second striker to leave the Vanarama National League South Beavers within the last few days after Marvin Morgan make an instant return to Bath City after just a few weeks in south west London.
Dowson will now look to add to his forward line as the club’s recent good form has seen the side move up the table.
Back-to-back wins over Whitehawk, and joint leaders St Albans City last night, means Hampton are moving forward.
“We wish Ryan all the best,” said Dowson on the club’s official website. “He’s always done well for me and I’d be happy to help him find a new club.”
Hampton’s next game is this Saturday at the Beveree and it will see a quick return for Morgan, who will travel with Bath City to the capital.
