ESPN.com insider Andy Katz reports that, according to a source with knowledge of the situation, the Chicago Bulls and Miami Heat are making offers to the Celtics for the No. 25 pick with the intent to land Boston College guard Reggie Jackson.

Chicago has the 28th and 30th picks while Miami has No. 31.

The Heat have made a promise, according to multiple sources, that they would take Jackson at No. 31. But Chicago is trying to get him before that to ensure that he isn't grabbed by another team, such as Dallas at No. 26 or New Jersey at No. 27. The Bulls, according to a source, are trying to move No. 30. Boston is not opposed to moving back to No. 30 or No. 31.
