FINN RUSSELL faces an RBS 6 Nations ban after being cited for his dangerous tackle on Wales' Dan Biggar on Sunday.

The 22-year-old fly-half collided with his opposite number just as Biggar was leaping for a high ball during the first half of the 26-23 defeat at Murrayfield.

Russell caught Biggar's legs with his shoulder, causing the Ospreys half-back to land on his shoulder.

The New Zealand referee Glen Jackson showed the Scotsman a yellow card following the incident in the 30th minute, but the Wales head coach Warren Gatland claimed after the match it should have been red.

Wales had Jonathan Davies sinbinned for a dangerous tackle on Alex Dunbar moments later and Gatland said: "My initial reaction was the first was red and the second was yellow. Those were my gut feelings.

"But I'm looking at it from a Welsh perspective. The referee's got to make the call and you have to live with the decision and move on."

Russell has now been called to appear before a three-man disciplinary panel later this week by independent citing commissioner Eugene Ryan.

He is charged with breaching Law 10.4(e) which states players "must not tackle an opponent whose feet are off the ground".

He is also accused of breaching Law 10.4(j) which prohibits "lifting a player from the ground and dropping or driving that player into the ground whilst that player's feet are still off the ground such that the player's head and/or upper body come into contact with the ground".

One player Scotland will definitely have to do without is the Jon Welsh. The Glasgow Warriors prop has been ruled out of the rest of the Six Nations after fracturing his hand in Sunday's defeat.

The Scottish Rugby Union has confirmed the 28-year-old will now have to undergo surgery and will play no further part in the championship.

Welsh touched down for Scotland in the final seconds but his try was not enough to prevent Wales clinching their eighth successive win over Scotland. He will now miss the February 28 match against Italy in Edinburgh, the trip to Twickenham to face England on March 14 and the tournament closer with Ireland at Murrayfield a week later.

The Scotland medical team are also keeping a watchful eye over a number of other players.

Fellow prop Gordon Reid lasted just two minutes of the action on Sunday before he had to be stretchered off with a head knock and knee strain.

Although he is 'symptom free' from his bang to the head, given the nature of his injury, doctors are treating it as a concussion, meaning he will have to undergo the mandatory graduated return to play protocol.

Lock Richie Gray sustained an injury to his upper arm and will also be scanned at Spire Murrayfield Hospital before a further update is issued later this week.

Meanwhile, Sam Hidalgo-Clyne finished the game but later developed mild symptoms of a possible delayed concussion and will also be monitored by the Scots medical staff,

A spokesman yesterday added: "A number of other players have required treatment today and will be monitored by both the Scotland, and respective club medical teams."
