Boxing: Tua comeback fight

David Tua takes another shuffle towards resurrecting his heavyweight boxing career by stepping into the ring with a potential punching bag this weekend.

Tua laces the gloves tomorrow for his second comeback fight this year at the Hard Rock Casino in Florida - his first in the United States for more than two years.

He is fighting the physically imposing 1.93m, 122kg Cisse Salif, and at 1.7m and 109kg, Tua gives away a distinct height and weight advantage.

Salif, 34, boasts 16 knockout victories from 17 bouts but has little experience against known boxers.

One of Salif's knockouts in 2003 was against a boxer with a 0-29 record.
