The Seattle SuperSonics are on the verge of solidifying their center position by closing in on an agreement with Vitaly Potapenko. An announcement could come this week.

It is not clear what the terms of Potapenko?s contract will be, but it is thought that his salary will be about $3 million.

When Jerome James signed a $30 million contract with the New York Knicks earlier this summer, the Sonics were left at center with second-year player Robert Swift and rookie Johan Petro.

Though the Sonics spoke with free agents DeSagana Diop and Andrew DeClerq, they decided to bring back Potapenko.
