Yeah... I thought earlier he'd started terribly but eventually got to grips with it & was just allowing the physicality but then reverted again. Some frankly odd decisions in both directions.
Nah, it was after he got fouled. Their player moaned about the decision (despite being an obvious foul) so assumed he was booking him for dissent but then showed it to Sheaf instead.
I agree it's awful (& doubly daft in that situation) but you can't book him for that.
Only thing I can think is he asked him to book their player? 🤷🏼♂️
