ABERDEEN boss Derek McInnes today confirmed keeper Joe Lewis could be out injured for up to three months.
The initial prognosis had been that Lewis would be sidelined for four weeks to two months.
The 30-year-old will tomorrow undergo surgery on ligament damage to his left knee sustained in the 2-0 loss to Rangers at Ibrox last week.
Danny Rogers will be in goal against Ross County in Dingwall tomorrow having started in the 3-1 defeat of Kilmarnock at the weekend.
However McInnes is still hopeful of signing a keeper on a loan deal until the end of the season before the winter transfer window closes at midnight tomorrow.
Newcastle United keeper Freddie Woodman is understood to be on the Dons’ radar.
Woodman, 20, is third choice at St James’ Park and was an U20 World Cup winner with England last summer.
McInnes said: “Joe saw a specialist on Monday night and will get his operation tomorrow.
“He will be out somewhere in the region of between two to three months.
“Hopefully it will be nearer two.
“The operation will start that process.”
Meanwhile Ryan Christie will return from a knee injury to face Ross County tomorrow night.
The on loan Celtic attacker missed the defeat of Kilmarnock but has returned to full training.
Striker Stevie May is ruled out for tomorrow’s trip to Dingwall with an ongoing ankle injury.
