HEAT: Udonis Haslem signed a one-year, $2.3 million deal to remain with the team for what will be his 15th season.

CAVALIERS: Looking to close the gap on the champion Golden State Warriors, Cleveland is in contract talks with free agent guard Derrick Rose, a person familiar with the negotiations told The Associated Press.

Rose, whose career has been sidetracked by injuries, could sign a one-year deal for the veteran’s minimum.

Cleveland has salary cap issues and is limited in what it can offer Rose, who made $21.3 million while playing in 64 games for the New York Knicks last season. first reported the Cavs’ pursuit of Rose, 28. Other teams, including the Los Angeles Lakers, are interested in him.

The Cavaliers signed free agent Jose Calderon last month as a backup to All-Star point guard Kyrie Irving. Rose, if healthy, would be a better option than the 34-year-old Calderon.

JAZZ: Utah signed big man Eric Griffin to a two-way contract.

The 6-foot-8, 205-pound center/forward played in Israel last season, averaging 14.9 points and 7.1 rebounds.
