Heaven was on the bench for Monday night’s Premier League home defeat to Everton.
The teenager has made two senior appearances in the division this term, during the 1-1 draw at Fulham and also coming on in the 4-2 win over Brighton & Hove Albion, when he assisted the second of Bryan Mbeumo’s goals.
He started the Carabao Cup tie against Grimsby Town as one of the three centre-backs.
