ADAM Voges, 35, is poised to become Australia's second-oldest Test debutant tonight.
The West Australian is expected to come into the national team to play the West Indies at the expense of fellow veteran Chris Rogers, who has been diagnosed with mild concussion.
Rogers was ruled out of the first Test in Dominica after being hit on the helmet while batting in the nets.
Team doctor Peter Brukner said after making the diagnosis, he made the call to rule Rogers out of the match in line with Cricket Australia's policy on concussion.
"I assured Michael (captain Michael Clarke) if it was him or anyone else we would make exactly the same decision," Brukner said.
It is anticipated Shaun Marsh will open the batting alongside David Warner, while Voges (pictured), who made 1358 runs in the Sheffield Shield last summer, will bat in the middle order.
The Aussies are expected to play spinners Nathan Lyon and Fawad Ahmed on the traditionally slow deck at Windsor Park.
