Nottingham Forest have shown an interest in Stevenage's head of recruitment Leon Hunter, according to the npower League One club.
Reports emerged last week that Forest's Kuwaiti owners, the Al-Hasawi family, were weighing up a move to bring Hunter to the City Ground as director of football.
Forest have a gap in their hierarchy after the Al-Hasawis controversially sacked long-serving chief executive Mark Arthur and dismissed Reds legend Frank Clark from his ambassadorial role last month.
Chief scout Keith Burt was also given the boot along with Arthur and Clark.
Stevenage chairman Phil Wallace told the Comet: "They (Forest) are not the first club to show an interest in him and I doubt they'll be the last since he's a talented young man with an extensive knowledge of British and overseas players and agents.
"However, he's loving the role at Stevenage and has a high level of autonomy and responsibility so I don't think it will be that easy for him to be enticed away.
"However, as with professional players, if any individual working in football has the chance to move to the highest level, I'm sure he or she will do so."
McGrath, club captain at Albion, has been unable to force his way back into the Brewers' starting line-up following a five-month absence with a foot injury.
The 32-year-old will remain with the Minstermen until March 11 and is reunited with manager Gary Mills, who he played under at Tamworth.
Despite being allowed to leave the Pirelli Stadium, Burton boss Gary Rowett insists McGrath remains part of his plans as the team chase promotion from League Two.
He said: "I've done this reluctantly, in a way, because characters like Macca are the sort of people I want around the club.
"I had hoped that I would be able to find him a place back in the side before now but, since he had that bad injury, the form of Lee Bell and Robbie Weir in the middle has been too good to disrupt.
"I know John is desperate to play and, with him going to York, he will now have a month of League Two football.
"I hope that means that we will get an even more match-fit Macca coming back to us later in the season."
