Six Nations: Scotland interim boss Scott Johnson frustrated after defeat

Scotland interim boss Scott Johnson refused to blame the referee for the 28-18 RBS Six Nations defeat to Wales.

Scrum issues

The scrum was particularly troubling for the hosts at Murrayfield, with Johnson insisting his side weren't trying to bend the rules in their favour. "What frustrates us is that we have a world-class front row. We try to scrum square. We don't teach them any tricks," he added. "Our scrum coaches are adamant that's the case. But we are getting nothing from it, and we haven't for three weeks. "Where we are struggling is that when the referee says set, that's go. But some sides are getting half-cued and not going at all. So there is an illusion that you are going early - when the other mob aren't going. "We don't coach that but we have been caught with our pants down a few times." Scotland flanker Richie Gray was carried off midway through the first half with a nasty looking hamstring injury. "He's in a pretty bad way," Johnson said. "It's more hamstring but we're not sure of the depth of that. He'll play again this season, I'm sure of that. But it will be a significant time away from the game."
