Hull chairman Adam Pearson claims to have read some "pretty reasonable" speculation over the identity of the club's next manager but insists there are more candidates.
Former Crystal Palace, Charlton and QPR boss Iain Dowie appears to have emerged as the front-runner to succeed Phil Brown, who was sacked by the Barclays Premier League strugglers on Monday.
Pearson is hoping to have a new man in charge before Saturday's trip to relegation rivals Portsmouth and he says the search is moving forward quickly.
"We've got a pretty tight list and we're working through it," Pearson told the club's website, www.hullcityafc.net.
"We're working through this exercise as quickly as we can, but obviously we want to explore every possibility.
"I think all the names mentioned are pretty reasonable. There are a few who the press haven't picked up on yet that we're talking to and it's always nice to have a couple of secret ones tucked away.
"I think we'll be able to bring that to the fore over the next couple of days."
Former Southampton and Northern Ireland striker Dowie, 45, first made a name in management at Oldham before moving on to Palace.
An ill-fated stint at Charlton followed before further spells with Coventry and QPR.
He was involved in a similar fire-fighting job last year as he joined Alan Shearer's coaching staff at Newcastle but was unable to help save the club from relegation.
Caretaker boss Brian Horton, himself a former Tigers manager, former Bolton chief Gary Megson and ex-England man Terry Venables have also been named as candidates along with Mark Hughes and Paul Jewell.
