England prop Alex Corbisiero insists he won't be making up the numbers when he joins the British and Irish Lions squad in Australia.
Corbisiero was due to play for for England against Argentina in Salta on Saturday but was called up as cover for Ireland front-rower Cian Healy, who suffered an ankle injury in the Lions' 69-17 victory over the Western Force and also faces a biting allegation.
Despite going over as a replacement, Corbisiero is convinced that he can win a place in the Test squad.
"I am going there to be first choice and to put my hand up," Corbisiero told Press Association Sport.
"It's going to be a big challenge and there are so many quality players out there. Just to go out there is amazing, but once I'm out there I want to get in the Test team.
"I am really excited. I feel very proud to be included and involved in something as prestigious as the Lions."
The Northampton bound prop was informed of his call-up by England coach Stuart Lancaster and will take four flights from Salta to Brisbane, via Buenos Aires, Santiago and Sydney.
"I was really looking forward to the first Test against Argentina," added Corbisiero.
"We have put a lot of hard work in and we have got an opportunity to put a statement down - Argentina is a hard place to win so part of me is gutted to miss that but part of me is excited to be out there with the Lions, which is one of the most prestigious things in rugby."
Corbisiero was a contender for a spot in the initial Lions squad but sustained a knee injury which limited him to just five starts for London Irish and two for England.
"This season was frustrating with injuries and that took me out of the running for the Lions," he explained.
"I only had a run of two games by the time they picked this squad.
"It was on my radar as a goal this season and I am very grateful I have ended up there."
