"It was fantastic being part of such a great team performance on Thursday night.

"This is the worst possible thing that could happen after breaking back into the team.

"Hopefully I'll get back as quickly as possible so I can help the team to win trophies.

"I know I'm out of the next leg but I know my team mates can finish the job," added Cousin.
