Scotland Test players 'involved in Glasgow street fight' It has been suggested that the three Scotland players, two of whom are in the current Test squad, and another player who has been capped at international sevens level, are the subject of a police investigation following an alleged assault that left Ally MacLay, an amateur club player with Glasgow Hawks, with head injuries. Brown said: "There's no doubt it is getting tougher. If you look through the whole squad there is a lot of competition for every place. There's no one who is absolutely nailed on to start. That's got to be a good thing. Scott is keen to build a lot of depth in the squad. He started that last season, especially on the summer tour. A few guys came in, were capped and did well. I think it's an exciting time. The squad is growing. The depth of talent is growing and that has to be a good thing. Brown captained Scotland throughout last season's RBS Six Nations Championship and then led the side against Samoa when they met in Durban in June. However, the 31-year-old was taken off with ankle ligament damage after 40 minutes, and returned home to have an operation a few days later. In his absence, the captaincy was taken by Greig Laidlaw, who led the team against South Africa and Italy over the next two weeks. Laidlaw is now favourite to continue as captain, if only because his goal-kicking responsibilities mean he is one of only a few players virtually guaranteed to start this month's matches. Brown, however, said he would happy to step in if required. "There's no doubt it is a huge honour," said the 58-times-capped player who returned to club action six weeks ago after a three-month lay-off. I've been lucky enough to do it in the past and if I get to do it again I would love to. Glasgow coach Gregor Townsend has moved scrum-half Niko Matawalu, who was cleared of a charge of biting Munster's Donncha O'Callaghan earlier this week, to full-back for the Connacht clash. Matawalu has played the position for Fiji in the past and Townsend said he was confident the player would thrive there again.
