KENNY Miller and Lee Wallace are consulting with their advisors and PFA Scotland after finally receiving correspondence from Rangers about their suspension from the Ibrox club.

Miller and Wallace were told to stay away from training at Auchenhowie and games at Ibrox earlier this month while an investigation was carried out into a dressing room bust-up that followed the William Hill Scottish Cup semi-final.

The club vice-captain and captain were allegedly involved in heated exchanges following the 4-0 defeat to Celtic at Hampden a fortnight ago today even though neither of them played in the match.

Graeme Murty, the Rangers manager, revealed on Friday that he had needed to deal with “problems in the changing room” since taking over from Pedro Caixinha back in October and stated he had now addressed the issues he faced.

It appears doubtful that Miller, the 38-year-old forward whose contract expires next month, and Wallace, the 30-year-old left back who has a year left on his current deal, will play for the Ibrox club again.

Neither player will be at Parkhead today when Rangers take on their Glasgow rivals Celtic, who can clinch the Ladbrokes Premiership if they win, for the final time this season.

The pair have needed to wait nearly two weeks to learn the exact reasons for their suspension and are now speaking to their representatives as well as PFA Scotland after being contacted by their employers.

Lee McCulloch, the former Rangers captain who played with both Miller and Wallace, yesterday expressed the view they deserved to be punished if they had “overstepped the mark”.

However, speaking on the Off The Ball programme on BBC Radio Scotland, McCulloch stressed that he would expect the duo to speak out after such a bad result and described the episode as “weird”.

“If Lee Wallace as captain doesn’t have something to say after being beaten 4-0 by your biggest rivals then I would ask questions of him,” he said.

“I don’t know if he’s overstepped the mark. In modern day football things have changed. Now you can’t really say much. The line has moved. If Kenny and Lee have crossed the line then they deserve to be punished. But if not? It’s just weird.”

Meanwhile, Rangers misfit Carlos Pena has sensationally been sacked by Cruz Azul due to "alcohol abuse" after he was caught urinating in a fountain in his team's hotel.

The 28-year-old midfielder returned to his Mexican homeland in January after former Rangers boss Pedro Caixinha signed Pena on loan following an unsuccessful first half of the season at Ibrox, after his £2 million arrival in the summer.

But his time at Cruz Azul has been a complete disaster and has started only two matches for the Mexico City club. So lacklustre were his performances that his own fans booed him.

Last week, he was caught buying a six-pack of beer straight after training at a shop outside Cruz Azul's La Noria complex while still wearing his club's kit.

That prompted Cruz Azul to carry out an internal investigation on Pena, led by club president Guillermo Alvarez.

And it's emerged that Pena was intoxicated in his own team's Royal Pedregal Hotel and was caught by hotel management urinating in a fountain in the hotel grounds.

The incident is believed to have occurred later in the same day as he was sighted buying beer. Pena also reportedly became abusive to hotel staff who tried to return him to his room.

And, after Sunday's final game of the first half of Liga MX against Veracruz, Pena's loan deal will be terminated and he will return to Rangers.

Sources in Mexico have revealed that Cruz are able to terminate the loan deal early because they had certain clauses regarding his behaviour inserted into it, which Pena has broken.

And it's been reported in Central America that Pena is considering an offer from Cruz Azul to attend an alcohol rehabilitation programme before he returns to Glasgow.

Last week, the Portuguese manager admitted Pena could be binned. He stated: "Carlos should know that sometimes in life, people don't get a chance like he has had...and certainly not two.

"So I have to decide what intervention to take with him. These range from a variety of fines or we can end his contract now.

"He is under contract until the end of the year, but in extreme cases, we can call it off and say to him 'thank you Carlos and goodbye'."

Rangers now face the nightmare prospect of the return of a player costing them up to £20,000 in wages who still has two years left of his contract.
