The New Jersey Nets' trade with the Portland Trail Blazers for forward Shareef Abdur-Rahim has been put on hold after questions arose during his physical examination, the Nets said Thursday.

The Nets did not disclose the nature or cause of the questions.

The 29-year-old Abdur-Rahim missed 22 games with the Blazers last season after undergoing surgery in mid-January to address loose particles in his right elbow.

New Jersey agreed to a six-year deal last month with the veteran forward, who has averaged 19.8 points and 8.1 rebounds during his nine-year career with Vancouver, Atlanta and Portland.

Nets president Rod Thorn was scheduled to address the issue Thursday afternoon at the Nets' practice facility. The team has until Aug. 12 to complete the trade.
