Days after coming up short in the national championship, the Top League's Panasonic Wild Knights bolstered their roster with the addition of Teikyo University star Rikiya Matsuda.

The 22-year-old back made his debut for Japan last summer against Canada and followed that by appearing in both tests against Scotland, starting the final game at fullback.

Although a star for Teikyo, which has won eight straight university championships, Matsuda will have his hands full competing for playing time on a team that boasts emerging star Takuya Yamasawa and two-time Top League MVP Berrick Barnes.
