Jut been announced https://www.efl.com/news/2021/may/play-off-semi-finals-appointments/ we get Harrington and Brooks names dont stand out but I would have to look at games they reffed to jog my memory
Apparently your boy Brooks was the ref for our 3-2 at Bournemouth and the other bloke has reffed us just once. Looks like Swansea have conceded a couple of penalties and a red with those refs this season.
Brooks is highly thought of and tipped for promotion himself. Playoff semi refs are usually SG1 but with the PL still playing, this year we get what are considered the top 4 SG2s - with the top 2 getting 2nd legs.
