The Knicks and Brewer are closing in on a buyout agreement that will make the former Minnesota swingman a free agent, sources close to the situation told ESPN.com.
Because Brewer will be officially released before March 1, he's eligible to play in the playoffs with another team.
Sources say Boston, San Antonio, Oklahoma City and Dallas are among the teams with the most interest in Brewer, who joined the Knicks only last week as part of the Carmelo Anthony deal.
The Celtics had previously tried to acquire Brewer from Minnesota before the Anthony trade went through.
