Dominic Solanke scored his 20th goal of the season to help 10-man Bournemouth move back into second place in the Sky Bet Championship with an incident-packed 3-1 win at home to Birmingham.
Ryan Christie and Jaidon Anthony were also on the scoresheet as the Cherries made amends for Sunday's shock FA Cup defeat at home to non-league Boreham Wood.
The hosts had Colombian midfielder Jefferson Lerma sent off in the second half two minutes before Onel Hernandez briefly made it 2-1.
Bournemouth are back up into the automatic promotion spots thanks to Blackburn being beaten 2-0 at Ewood Park by Nottingham Forest, who are now in the play-off places.
