As revealed in the Evening News on Sunday, the Scotland international could be set for a Tynecastle switch if he could find a way out of the remaining 12 months on his Hull contract.
Speaking to the media on Friday, Cathro refused to go into details about the potential move, though did confess he is looking to bring in another goalkeeper following 23-year-old Hamilton’s error-strewn end to last season.
He said: “I saw that was something that was written about. I’m not going to allow that to be talked about any further.
“We have two goalkeepers who we are doing a lot of work with now. There may be some things we adjust into the new season.
“It is an area of the team where we will look in the market and see if we can find someone to help us.
“Whether we do that or don’t, I don’t know.
“But in Jack we already have a goalkeeper who has significantly more experience than goalkeepers tend to have at his age.
“He’s someone we fully intend on developing and supporting. I have no doubt he will be a future number one for this club.”
