According to the Daily Record, the Easter Road club are keen to extend the player’s current deal, which runs until the summer of 2023.
Porteous was previously the subject of a failed transfer bid from Millwall in this year’s January transfer window.
Hibs have been working hard behind the scenes this season to get their most-valued assets tied down to improved and longer contracts. Martin Boyle agreed a new deal earlier in the summer, which saw the removal of a £500,000 release clause, while talks are still ongoing with striker Kevin Nisbet.
The two players, along with Porteous and highly-rated teenage left-back Josh Doig, were serious candidates to potentially leave the club in the summer, but Jack Ross’ side have remained firm with regards to interest transfer market.
