Johnson said he has spent enough time carrying water, tackle-bags and balls

London Irish lock Gary Johnson is determined to make his mark on the team after years on the sidelines.

The 24-year-old, who joined the Exiles' academy in 2003, is appearing regularly with other second-rows injured.

He told BBC Radio Berkshire: "Nobody likes to see your team-mates injured, but from my point of view, I need to take these opportunities when I can.

"Most of the fans know me as the water boy. I've worked hard for many years and I'm glad I'm getting a chance."

When Nick Kennedy pulled out with sickness on Saturday against Leicester, Johnson was partnered in the second row by Nic Rouse, on loan from Nottingham.

He admitted it was a surprise to find himself as the senior partner.

"It was exciting and it was frightening too, I must admit. I was confident but there was a brief moment of 'oh dear' but I quickly wanted to get on with the job and take the challenge on.

"I've had plenty of time waiting for it and I've had good teachers in both Bob Casey and Nick Kennedy. But I'm relishing the challenge and looking forward to taking it on further.

"I think Nic did very well and grasped the line-outs very quickly.

"There's quite a bit to take on board. We didn't want to throw too much at him, but during the week we worked hard with him and it paid off."

Johnson said with the return of Casey and Kennedy imminent, he is aware he has to be versatile to ensure game-time.

"The boys have a great reputation in the line-out, but also I want to bring something different to the park.

"I've also been looking a bit at playing at six, so when the boys are back and if I'm back on the bench, maybe I can cover six as well.

"I've looked at my body composition and I've worked hard on that over the summer and being more mobile is definitely going to help me out going forward."
