Take the recent game where an opposition player receives treatment and the 'ref' allows the player to remain on the pitch once the 'physio' has departed - absolute CHYTE, he obviously did not comprehend even the basic law concerning that incident. Never mind other 'treatment' handed out to Rovers players over the season.
Sorry! Can't allow this comment to stand unchallenged and as no-one else has corrected it I'll need to break my self-imposed exile to do so.
A rule change introduced for season 2016/17 by the International Football Association Board -IFAB, for Law 05 - The Referee, states the following.
"A player injured by a red card or yellow card foul can be quickly assessed/treated and remain on the field of play."
As either Connor Jennings or Cole Stockton (can't remember the incident with absolute clarity though do recall the yellow card) was cautioned, the referee was absolutely correct to allow the player to remain on the pitch once the physio had departed. If the card had NOT been brandished the player would still have been made to leave the field.
If anyone else wants to get themselves up to date with the law changes rather than ignorantly berating the referee for a correct implementation of the current laws, you can download the latest changes from here...
The document is at the bottom of the long list of the various laws.
