Former Rangers goalkeeper Cammy Bell says the club's big-money signing Kevin Kelsy must step up in Lawrence Shankland's absence. Scotland striker Shankland went off in the early stages of Saturday's 1-0 win over Motherwell, with manager Derek McInnes later saying it appears to be a "significant" hamstring injury. Shankland was replaced by Ryan Naderi, who scored Rangers' winner against the Steelmen, but Bell believes it will be Kelsy - signed from Portland Timbers on deadline day for a reported fee of £9m - who McInnes trusts to lead the line.
