A small group of Rangers fans have allegedly repeated the chants which offended Kilmarnock manager Steve Clarke last week.
Reports claim a section of the Rangers support were heard singing the song during Sunday's 5-0 Scottish Premiership victory at Hamilton.
After Kilmarnock were beaten by Rangers in the Scottish Cup at Ibrox on Wednesday, Clarke said he had been the target of sectarian abuse from some Rangers fans and accused them of living in the Dark Ages.
Clarke - who revealed he had been approached by Rangers over their managerial vacancy last year - later appeared at a media conference with his captain, Kris Boyd, to call for action and education over Scottish football's sectarian problems.
Former Rangers striker Boyd had been subjected to sectarian abuse by Celtic fans days earlier.
Rangers chairman Dave King offered a "sincere apology" to Clarke over the "unwarranted abuse" on Friday.
But Clarke was again allegedly abused by a small number of Rangers fans during the first half at Hamilton on Sunday, as they chanted the song which he had complained about in midweek.
A banner stating "Get well soon Steve Clarke" had earlier been unveiled by some visiting fans at the HopeCBD Stadium before kick-off.
"For me, at the risk of repeating myself, we don't want to hear that or see anything," said Rangers boss Steven Gerrard.
"I was quite clear in my press conference last week. There's no place for it. We want it to stop."
