Warnock claims that his newly-promoted squad should heed the performance of the Wanderers striker, who has earned a reputation as a tough centre-forward.
"I think Kevin Davies showed us what it was all about. Seven fouls he committed in the first half and he didn't get booked, and then he leaves his foot in to make sure he gets a free kick for the second goal," Warnock told Sky Sports News.
"He's a clever lad and he's been doing it all his career, so we have to learn a little bit from that and how they were professional away from home."
QPR now sit at the bottom of the Premier League on goal difference.
