The SuperSonics and Denver Nuggets are discussing a trade that would send Ronald ?Flip? Murray to Denver and bring former Sonics guard Earl Watson to Seattle, sources said Wednesday.

It is unclear if a trade will be consummated because the Nuggets (14-15) are talking with other teams in an attempt to upgrade a roster that many ? including coach George Karl ? predicted would win the Northwest Division.

Sonics general manager Rick Sund could not be reached for comment.

The Sonics would have to include several other players to complete a deal because Murray earns $895,000. Under terms of the collective bargaining agreement, the salaries of players traded must be within 15 percent of each another. Watson, who signed a five-year, $29 million deal this summer, earns $5 million this season.

If the Sonics put together an offer of Murray, Mikki Moore, Rick Brunson and Mateen Cleaves or Reggie Evans, they could get close to the total needed to complete a deal for Watson, who left the Sonics via free agency in 2002.
