The former St Pauli forward was in the right place to cleverly deflect Sam Morsy's shot past Lions goalkeeper Max Crocombe and give Rovers a half-time lead.

After Lyndon Dykes had levelled from the penalty spot early in the second half, Afolayan ran from halfway before firing in his second, while striker Andri Gudjohnsen added a counter-attacking third deep in added time.

That made it four consecutive wins over the Lions for Blackburn, their best run against them since 1990, while Millwall have not won at Ewood Park in 11 visits.
