Dont be silly,mate! Chagaev is not losing his reputation with this fight as you put it so nicely.It is a tune up fight for his upcomming encounter wiht Valuev.Chagaev was out of the game for quite a long time. As for the entire fight event with Chagaev there are some good undercard fights. Maidana vs Kotelnik will probably be more fun and more entertaining to watch than Chagaev vs that unknown Costa Rican. Boytsov,one of the most promising young heavies on this globe, will also appear on the undercard- as well as two other undefeated young heavies: Tereshkin and Wach. Unfeated supermiddle weight talent Gutknecht will test the deep waters by taking on Rubin Williams. Very good undercard in my humble opinion.
