Rangers set up a Scottish Cup fourth round clash with Celtic after thrashing League One Cove Rangers 4-0 on Sunday.
The Glasgow giants were paired together in the draw for the last 16, offering Celtic a chance to avenge Rangers winning the Scottish Premiership for the first time in 10 years.
The tie will take place on the weekend of April 17/18.
Rangers boss Steven Gerrard has insisted that winning the Scottish Cup is his priority for the remainder of the season rather than completing the league campaign undefeated.
The former Liverpool captain named a strong side at Ibrox and was rewarded with four first-half goals.
Jermain Defoe opened the floodgates before Kemar Roofe's quickfire double and Nathan Patterson's strike put the tie beyond doubt before the break.
