Claudio Yacob was replaced by Tony Pulis after escaping a second yellow card, but Guus Hiddink suggested he should have been dismissed.
Guus Hiddink says Tony Pulis took the role of the referee when he substituted Claudio Yacob after a controversial tackle on Oscar in the second half of West Brom's 2-2 draw with Chelsea.
Argentine midfielder Yacob was on a yellow card when he stopped a Chelsea break by hauling down the Brazilian, but referee Anthony Taylor allowed him to remain on the pitch.
