Rovers have signed striker Kwame Thomas on a short-term deal until January 2020.
The 6ft 3in former England youth international has agreed a contract after impressing manager Darren Moore while on trial at the club.
He said: “I’m very happy, for a while now I’ve wanted to get things sorted and know where I would be playing my football this season.
“Everyone knows each other and all the lads have felt me really welcome, that made it easy to settle in and for me to show what I can do.
“The boys have done really well and started the season off in good form, and from being involved in training with them I can see why.”
