Rangers survived a Scottish Cup scare to beat Partick Thistle 3-2 after sportingly handing the Championship side a second-half equaliser at Ibrox on Sunday.

Thistle led 1-0 at half-time through Kevin Holt's penalty, but Rangers looked to have turned the last-16 tie around when Antonio Colak headed in an equaliser before Malik Tillman scored in controversial circumstances.

The American international had gone down requiring treatment with Thistle set to hand possession back to Rangers.

However, Tillman robbed the ball deep in the Thistle half and ran through to round the goalkeeper and slot into an empty net.

Rangers boss Michael Beale responded to the visitors' protests by allowing Scott Tiffoney to run the length of the field to slot home an equaliser.

"Malik gets injured, he didn't see the ball's been kicked out. Naturally when he stands up, he thinks he's got to press," said Beale.

"We scored, it's controversial, but this club is built on high standards and we want the best for the game. I made a lot of mistakes today in terms of team selection but that wasn't one of them.

"It was the right decision. I don't want that hanging around (Tillman's) head. I felt it would've been unjust us winning a game in that way."

Rangers did go on to reach the quarter-finals anyway as Connor McAvoy turned Borna Barisic's corner into his own net four minutes from time.
