Cardiff assistant manager Kevin Blackwell took on the club's post-match media duties as Warnock had to leave the win over Burton Albion early to meet a transfer target.
However, Blackwell wouldn't reveal the player Warnock is chasing.
"I'm talking to you because Neil has had to catch a flight to see a player," said Blackwell.
"We're still looking at possible signings but in terms of preparation, the lads showed how much fitter they were second half and that's what we've been looking at.
"I can't tell you who he's gone to talk to as I think there will be other clubs looking at him as well."
