VERN Cotter explained yesterday that he had decided to omit Ryan Wilson from his Scotland squad for the Six Nations Championship even before the Glasgow forward was cited for an alleged offence in the game against Northampton at the weekend.

The national coach named a squad of 35, including Tim Swinson, who like his Warriors team-mate faces a disciplinary hearing in London today as a result of being cited after the Northampton game. But, while Swinson will be free to play against England a fortnight on Saturday if he is not banned for throwing a punch during his team’s Champions Cup defeat, Wilson will have to escape a lengthy sanction for his supposed offence - and thence persuade Cotter he is worth selecting.

The possible punishments for Swinson range from a two-week suspension right up to 52 weeks. Wilson, who has been charged with grabbing the testicles of Saints captain Lee Dickson, could face a 12-week ban if found guilty of a so-called low-end offence, although at the most serious end he could be suspended for anything from 24 to 208 weeks.

As well as explaining that Wilson had been omitted because of his lack of form, Cotter was keen to suggest that there was little in the supposed misdemeanour. “We made a decision with Ryan before he was cited,” the coach said. “We’ve been happy with the way he’s been improving, but we feel other players are playing better than he is at the moment.

“He’ll go through the hearing process. It seems to me he was just reaching for a pair of shorts, but there are other people who’ll make a decision.”

There are only two uncapped players in the squad, both props, Zander Fagerson of Glasgow and Rory Sutherland of Edinburgh. Mark Bennett is currently sidelined because of a shoulder injury, but Cotter believes he still has a chance of regaining fitness in time for the Calcutta Cup match. The centre’s Glasgow colleague, hooker Fraser Brown, is omitted because of his ankle injury but should be back playing in three or four weeks.
