I'm sorry but the doctors orders should always be prioritised, both for the good of the player and the good of the club. Clearly something had shown on a scan, and had it been aggravated during the match (luckily it wasn't), he could have ended up with a much more serious injury. That would've meant him out for key, potentially relegation-deciding Premier League matches, potentially months. This is coming from someone who thinks Berahino is a bit of a tosser and I've criticised him heavily in the past, yet on this score I don't blame him one bit. Very poor management, and I can only assume anyone who doesn't understand this must has very little understanding of human physiology.
