Cheers 👍
It may be a combination of my aging eyes and the camera angle but as far as I could tell, Obefemi shoved the Blackburn chap in the chest. Thought it had to be on the face for it to be a red card? As per the screenshot below, N'lundulu's preventative hand is actually closer to the Blackburn player's face than Obafemi's is.
Not tyring to defend Obafemi for the sake of it, as it was a daft thing to do regardless, but I couldn't see anything that warranted a red card (i.e. contact with face), unless my understanding of the rules are wide of the mark of course.
(By the way, talking of camera angles, that pitch level view was nigh on impossible to watch - the panning was far too fast due to the camera being too low. Need to get some elevation.)
