Boro are thought to be keen on bringing in fresh faces upfront with current strikers Afonso Alves and Tuncay tipped to leave the Riverside in the coming weeks following the club's relegation from the Premier League.

Hulse, who has struggled with injuries in the past, managed to feature 54 times last season in all competitions, scoring 18 goals.
