Well existing Covid cases and injuries to be precise.
What I mean is, they have no new Covid cases. It's purely injuries - and a suspension (Manquillo), although Hayden would be back.
According to the new 'Covid' rules, a club needs 14 players for a game to go ahead - but only players who have first team minutes (inc League Cup) count.
Newcastle played their first team in the League Cup (and lost). So they don't have to field their U23 players. They can just get a game postponed.
We played a load of kids in the League Cup (and some in PL), so fringe players such as Turns, Roberts, Richards, Leonard and Alzate count in our 14... grrrrr!
