RANGERS have tonight completed the signing of Jason Cummings on loan until the end of the season – and the striker’s fellow Scotland internationalist Russell Martin is set to join him at Ibrox tomorrow.

Cummings, who helped Hibernian win the William Hill Scottish Cup in 2015 and the Ladbrokes Championship last year, finalised the deal after undergoing a medical in Glasgow yesterday.

The 22-year-old moved to English Championship club Nottingham Forest in the summer, but hasn’t been a regular starter at the City Ground and has only netted one league goal.

Mark Warburton, the former Rangers manager, was sacked earlier this month after a disappointing run of form and it looks unlikely the Scot has a future under his replacement Aitor Karanka.

Cummings, who made his debut for the national team when he came on as a substitute against the Netherlands at Pittodrie in November, could join on a permanent deal in the summer if the loan goes well.

The centre forward is the fourth new player to join the Ibrox club in the January transfer window – Declan John signed from Cardiff City while Sean Goss of Queens Park Rangers and Jamie Murphy of Brighton both arrived on loan last week.

Meanwhile, Rangers could also agree a temporary deal with Martin, the Norwich City and Scotland centre half who has not been featuring at Carrow Road this season, later today.

The 32-year-old, who last played a first team game back in August, knows Murty, who worked as a youth coach at Norwich before moving to Rangers, and is keen on the move to the Premiership club.

Norwich and Rangers have agreed terms and the player is expected to undergo a medical in Glasgow tomorrow and complete the temporary switch.

Meanwhile, Steve Clarke, the Kilmarnock manager, revealed the Rugby Park club had little difficulty turning down the offer, believed to be in the region of £350,000, which Rangers tabled for Jordan Jones.

The 23-year-old winger, who made his debut for Northern Ireland when he came on in the first leg of his adopted homeland’s Russia 2018 play-off match against Swit-zerland at Windsor Park in November, only has 18 months of his contract remaining.

Speaking as he collected the Ladbrokes Premiership Manager of the Month award for December, Clarke said: "We didn't even have to discuss it too much - it was just a straight no. I have to say I thought the offer from Rangers was a long, long way short of the mark."

"If you look at Kilmarnock historically, if the price is right for the club and the deal is right for the player, then Kilmarnock football club is not a club that would stand in somebody's way and block their way."

Rangers have also been linked with their former player Steven Naismith and have made enquiries about Greg Docherty of Hamilton.
