Warnock was signed from Leeds United over the winter for an undisclosed fee, but has made just three appearances in total as he was sent off against Reading in the FA Cup on his debut.
“I know I didn't have a good start and that set me back, because it knocked my confidence a bit,” said Warnock.
“You always want to make an impression on your team and your new team-mates. I wanted to do that and probably got a bit carried away.”
Warnock is an experienced option to have coming into the team for the final stretch of games.
He was probably hoping to play a part in an automatic promotion campaign for the side, but the Rams still have a very good chance of going up through the play-offs.
All they can do is win games and that’s made easier if the defence can keep clean sheets and take a bit of pressure away from the attack.
Warnock has had plenty of time to mull over things following the red card on his debut and that should have given him the motivation to make up for it and play well over the rest of the campaign.
He’s a player who knows all about the pressure of the run-in and is a good option for Steve McClaren to turn to when things get a bit tense over the next few weeks.
