Callum Rowe has joined Exeter following his release from Aston Villa.
The 21 year old has signed as one year deal.
"Callum came to train with us for a couple of reserve matches at the end of last season. He has a fantastic physical profile and he really impressed us," said manager Matt Taylor.
"We saw enough of him to give him that opportunity. Callum is of a certain age where he will continue to learn, and we hope he can remain fully fit and influence this side."
Rowe had a short spell on loan with Hereford last season.
He joined in January and made his debut at Stamford in the FA Trophy. However a knee injury limited his appearances.
