Following Glasgow Rangers' crunch Old Firm clash with Celtic on Saturday afternoon, Steven Gerrard's side have been dealt a huge injury blow.

What's the news?

Despite gaining the upper hand over their arch rivals in the title race, Gerrard would have every right to be concerned after Kemar Roofe was substituted at half-time after appearing to pick up a knock.

The Ibrox boss then told Rangers TV, as quoted by The Daily Record: "It was on our minds to make a change in the first 45 because we weren't happy with the front three.

"But a stroke of luck, not in terms of the injury because Kemar (Roofe) has got a niggle in his quad, we'll have to assess that and hope he gets back fit, but it actually played into my hands in terms of getting Ianis on the pitch who I thought was outstanding in the second half."

It was revealed shortly before the second Old Firm derby of the season that Scott Arfield and Ryan Jack had been ruled out of the clash with Celtic due to injury.

Likely impact?

Roofe has been an ever-present in Gerrard's side ever since he first arrived at Ibrox from Anderlecht in the summer, with the Jamaican striker having started 12 of his 15 appearances in the Scottish Premiership this season - he also scored a memorable goal from inside his own half against Standard Liege in the Europa League.

Speaking at the start of this season, former Dundee and Leeds United defender Barry Douglas was effusive in his praise for his former teammate, saying: “He’s a good guy to be around and a very humble lad too, which, going into a club that size, is a massive attribute.

“Roofe’s very grounded so all the ingredients are there for him to do well.

“He’s a great acquisition for Rangers, and I think he’ll be successful there because he knows where the back of the net is.”

Roofe has been in prolific form since the start of the season, providing 12 goals and 2 assists in 21 appearances across all competitions, via Transfermarkt.

With a trip to Aberdeen next on the agenda, there's no doubt his presence will be sorely missed ahead of a huge game against their Premiership rivals, after he got himself on the scoresheet during the 4-0 win at home to the Dons last time out.
