Scotland quartet face court date over alleged assault in Glasgow Grant and Maitland were part of the British and Irish Lions tour of Australia this summer and are both in the Scotland squad for Sunday's game against South Africa at Murrayfield. Wilson has played four times for Scotland and is currently recovering from injury. Hughes is a member of the Scotland Sevens squad. Grant, Maitland and Wilson also play club rugby for Glasgow Warriors. A Warriors" spokesman said: "As part of our own procedures we would always instigate an extensive internal inquiry into any allegations of player conduct falling below the high standards that are part and parcel of Scottish Rugby's ethos and values. We are continuing our own internal investigation into an alleged incident last month, while at all times co-operating fully with the authorities. The club will be making no further comment at this time. A spokesman for Scottish Rugby said: "We have been kept fully apprised of the alleged incident and we will continue to monitor closely any developments. We cannot offer any comment on the alleged incident at this time. However, we do reiterate that it is imperative that the values of our game are upheld by all those involved with the sport. Meanwhilee Scotland prop Alasdair Dickinson is still hurt by the summer defeat against South Africa. And he will take that memory into Sunday's meeting determined to atone for the controversial 30-17 defeat in Nelspruit in June. But the Edinburgh forward knows the tourists will be equally stung by the encounter after Scotland charged into a 17-6 lead. The Springboks took the lead when Scotland lock Jim Hamilton was in the sin bin following a contentious decision to give him a yellow card for a push, and they went on to secure a win that still rankles with Dickinson. The 29-year-old said: "We are disappointed in how we ended that game. There was an opportunity to win it and that still sits with us. That's an extra bit of fuel for the fire I guess but they are the same. They got a bit of a scare so they will be wound up just as much as us, so it will be a physical game.
