It has been reported that Doidge is on the Black Cats' list as a potential alternative to Charlie Wyke of Bradford City for Sunderland, who will play in League One next season after getting relegated from the Championship.
Scottish Premiership club Aberdeen are also claimed to be interested in the 25-year-old Welsh striker.
Risky signing for Sunderland?
Doidge did well for Forest Green last season, as the striker scored 20 goals and provided five assists in 42 League Two appearances, according to Transfermarkt.com.
The 25-year-old striker, though, would be a risky signing for Sunderland, as the Black Cats need someone who knows League One well and has been a success in the division.
