Career

Prosser trialed for the Wales team as early as the 1931/32 season but did not gain his first cap until the 1934 Home Nations Championship, when he was selected to face England.

Out of 13 new caps on the day, five, including Evans, never played for Wales again, but Prosser returned in the next two games of the tournament, now led by the more reliable Claude Davey.
In 1935, Prosser was given another chance to face international tourist when Neath joined up with Aberavon again to face the touring All Blacks. Although the joint team lost to New Zealand Prosser brought his familiar style of offensive forward play through the All Black back division, and did enough to gain the favour of the Welsh selectors.
Prosser played his final game for Wales one week later when he was chosen to face the same touring New Zealanders.
