Blackburn Rovers have signed former Watford youngster Aaron Tumwa.
The 19-year-old defender was released by the Hornets at the end of last season but will now link up with the development squad at Ewood Park.
Tumwa has been training with Gary Bowyer's men all summer and has managed to earn himself a one-year contract.
He was loaned out to non-league Wealdstone last year.
