Four were added on, then Reading made a sub within it. Probably slightly over the time, but not much.
Sub should be 30 seconds, ref should have blown before the throw in was taken.
Unless it took longer than 30 seconds.
If they didn't make the late sub, they wouldn't have lost a goal. It's a daft idea because it makes no difference at all.
I timed him, it was less than 30 seconds.
Then they'll still add on 30. And it's then natural to round up subconciously.
