He had him jogging in his corner, it doesn't take 10-15 seconds to check that lol. Cmon bro. But it was a good storyline so can't hate .
All refs do this. You can't just stand. You have to be standing by 10, but then they'll check to make sure the fighter can go on, and the fighter has to respond. They'll do a number of things - tell you to raise your gloves, ask can you continue and check your eyes, ask you to walk to corner and come back and fight. If you've heard of a standing 8 count, it's the same practice. Ref did a great job.
Actually, more credit should be given to Fury. He did the right thing by giving himself a couple of seconds to regain focus before trying to stand.
