Corey Brewer has been placed back on the trading block by the Minnesota Timberwolves.

The Houston Rockets and Cleveland Cavaliers, sources said, remain the most interested suitors for Brewer, but have also been joined by the Los Angeles Clippers.

Flip Saunders, after calling Brewer "too valuable to trade" on Nov. 20, publicly acknowledged last week that the Wolves' many injuries and subsequent struggles to compete in the difficult West have forced Minnesota to concede that the team is shifting from a "retool" mode to a "rebuild."
