McCall, 50, returned to the club he made over 250 appearances for on Thursday, assuming the role as manager until the end of the season.
He inherits a squad who are drawing far too regularly, and McCall needs to turn the club's form around if they are to return to the Scottish Premiership.
In January, Rangers managed to snap up five Newcastle loanees thanks to shareholder Mike Ashley, who of course owns the Magpies.
Defenders Kevin Mbabu, Remie Street, midfielders Shane Ferguson, Gael Bigirimana and forward Haris Vuckic all arrived from St. James' Park until the end of the season in a bid to give Rangers a boost.
Vuckic is making a strong impact at Ibrox, and has now scored twice in his last two games, but the less about the rest of the loanees, the better.
Streete suffered an injury on his debut and has appeared since, whilst Mbabu, Ferguson and Bigirimana haven't even featured for Rangers since arriving.
Now, McCall has told the BBC what the future hold for Streete, Mbabu, Ferguson and Bigirimana - and it isn't good news.
Whilst Vuckic looks set to play a part under McCall, the new Rangers boss told the BBC that it's unlikely the other four Newcastle loanees will even play for the club.
"If you take the four lads [January loan signings] from Newcastle, who probably won't kick a ball for us, out of the equation, it's not as big a squad as you'd imagine," he said.
Ashley's influence at Rangers has diminished since Dave King's consortium won control of the club - and it would be little surprise to see the four players in question head back to Tyneside before the end of the season.
