'It was quite difficult to deal with at times and a bit unpredictable'

Leigh Halfpenny is two games into his comeback from concussion. The full-back sustained a head knock after a tackle by Samu Kerevi during a 9-6 victory over Australia on November 10, a challenge which Warren Gatland criticised in the aftermath.

He missed the start of the Six Nations because of the problem, finally returning to the field for the Scarlets in their 43-21 PRO14 win over the Cheetahs on February 24th. He also played an influential part in a narrow 10-6 victory over Munster last Saturday.

"It is great to be back and I am loving being back on the field with the boys. It has been a difficult couple of months and it was not the best of injuries." Halfpenny said in an interview with Y Clwb Rygbi.

"It was quite difficult to deal with at times and a bit unpredictable."

"The head is all good now and it was great to get another 80 minutes under my belt and be out there with the boys."

Halfpenny's return has paved the way for a possible international recall, but he knows he may have to bide his time following Wales' impressive 21-13 win over England last time out, particularly with the form of Liam Williams who picked up the man-of-the-match at the Principality Stadium.

"We will see what the selectors go with, but looking at the boys there they have been outstanding. That game against England was awesome."

Wales are the only side that can achieve a Six Nations Grand Slam this season and face Scotland at Murrayfield this Saturday.

"There is a great feeling in camp and it is a massive game at Murrayfield for this tournament. So it's an exciting week ahead for the squad," Halfpenny said.
