Darlow moved from Nottingham Forest to Newcastle in the summer, but he has played just one game.
The former Nottingham Forest stopper said: “You can be out the side one game then in for the rest of the season. It’s about training as hard as I can and pushing Tim as hard as I can and waiting for my chance. As second-choice keeper, it’s about patience, and I knew the situation when I came up here.”
Darlow completed his switch to St James’ Park this summer, having actually signed for the club last year, along with Forest defender Jamaal Lascelles.
He has played just one game so far for McClaren’s side, starting and lasting the full 90 minutes in a 4-1 victory over Northampton Town in the League Cup.
However, the English ‘keeper was always going to be behind Tim Krul in the pecking order for first-team action, with Dutch international Krul one of the best goalkeepers in the Premier League.
It will be hard for Darlow to break in ahead of Krul, and it is likely that he will be restricted to cup appearances for the Magpies this season.
Darlow will have to do all he can in those games to show he is ready for the step up to Premier League action, and be hoping that Krul suffers a loss of form which causes McClaren to look at the Englishman as his first-choice stopper.
