Rangers ended a tumultuous weekend on a positive note with a 2-1 win over Morton in their William Hill Scottish Cup fifth-round clash at Ibrox The Govan club was rocked by news of boss Mark Warburton’s resignation late on Friday night with confusion following when the club statement announcing his departure was reportedly denied by the Englishman. Under-20s boss Graeme Murty was placed in temporary charge for the visit of the Championship side but the Gers supporters were further stunned when Michael Tidser fired the Greenock men ahead in the seventh minute with a fine volley.
