Adam Hastings: Knee injury to fly-half 'gutting' says Gloucester boss

The knee injury that has ruled Scotland fly-half Adam Hastings out of the Six Nations is "gutting" says his Gloucester boss George Skivington.

Hastings went off in the second half of Gloucester's Challenge Cup win against Castres having scored a try and kicked another eight points.

He withdrew from Scotland's Six Nations team on Tuesday to see a specialist.

The 27-year-old had only recently returned to his club after a "hellish" 18 months disrupted by injuries.

"It's not great, he's hurt the other knee. He's had scans this week and he's going to see a specialist around if anything needs doing to it or what the procedure will be," Skivington told BBC Radio Gloucestershire.

"It's gutting for us, we haven't seen a lot of Adam in the last 18 months and he's just come back and played really, really well for a month or so and then a pretty innocuous bang.

"These things can go either way, they can be really lengthy or sometimes they can just do a little bit and sort it out but it's not good news that's for sure."

Hastings, who has 27 caps for his country, has played five matches for Gloucester since returning from injury to one of his knees in December.

He only played 10 games last season for the Premiership club after missing four months with a shoulder injury.

As well as the game against Castres, the number 10 also put in a stand-out performance in the victory away to Edinburgh earlier in the European competition before getting the international call-up.

"We missed him while he'd been out and he'd just been getting some traction, the boys were feeding off him and I think he was starting to enjoy his rugby and I thought he'd been playing really, really well the last couple of weeks," Skivington added.

"Obviously that performance up in Edinburgh was really good and had got him into that Six Nations squad effectively.

"The timing of it is really bad and we were just starting to feel in a rhythm with him there. Unfortunately that's the nature of the beast and we'll get him back as quickly as we can."
