Sky Sports understands that Hibernian are planning an approach for former Hearts right-back Fraser Mullen.
The teenage defender is available as a free agent after being released at Tynecastle.
Hearts opted against offering him fresh terms, despite the 19-year-old having graduated out of their academy ranks and into the senior squad.
Mullen could, however, be about to cross the city and sign for Hearts' arch-rivals.
Hibernian are looking to piece together a side that can improve on last season's disappointing bottom-half finish in the SPL.
Mullen's potential appeals to them, with the youngster having expressed a desire to kick on in his career after suffering a frustrating time with injury.
