Bradford's former England prop Garreth Carvell is on the verge of a dramatic return to Hull.
The 32-year-old joined the Bulls in the close season from Warrington on a two-year contract but looks set to be reunited with Hull coach Lee Radford, his former Black and Whites team-mate at the club where he made his Super League name.
Hull, whose need for a new front-rower increased after injuries last weekend to Liam Watts and Chris Green, confirmed their interest on Thursday, saying they are monitoring the situation.
"The club have been made aware of Carvell's availability and could look to formalise a deal for the Challenge Cup winner in the near future once his situation has been clarified," Hull said in a statement.
Carvell made 164 appearances for Hull from 2001-08, including two Challenge Cup final appearances, before joining the Wolves, for whom he played in last October's Grand Final.
Although Bradford chairman Mark Moore said at the weekend that coach Francis Cummins' squad had been "ring-fenced", it is thought that Carvell has made clear his desire to leave the club, who are in the middle of another crisis after OK Bulls Ltd was put into administration.
The Bulls say all the players have been transferred to a new company, Bradford Bulls 2014 Ltd, but the club are facing a possible points deduction and face a crucial meeting with the RFL on Friday.
The loss of Carvell would be a major blow to Cummins and his small squad with relegation returning to Super League this year.
Carvell, who toured New Zealand and Australia with England in 2010, has made just one appearance for the club, ironically against Hull in the Bulls' opening friendly on January 19, and was not selected against Castleford last weekend.
It is thought Carvell has already agreed to rejoin Hull on a one-year deal, with the option of a second season, depending upon appearances.
