After medical consultation, seven-time All-Star forward LaMarcus Aldridge is seriously considering a return to the NBA this season, sources told ESPN.

Aldridge abruptly retired with the Brooklyn Nets in mid-April after heart concerns sidelined him, but now is exploring the possibility of resuming his 15-year NBA career.

Aldridge is expected to have conversations with prospective teams in the coming weeks, sources said, and still ultimately needs an individual organization's medical clearance to sign a contract. Nevertheless, Aldridge, 36, has yet to make a final decision on playing again.

Aldridge said he experienced an irregular heartbeat during a Nets game against the Los Angeles Lakers in April, after which his condition worsened.

"For 15 years I've put basketball first," Aldridge wrote on Twitter at the time. "And now, it is time to put my health and family first."

Aldridge signed with the Nets on March 28 after agreeing to a buyout with the San Antonio Spurs, where he had spent the previous 5½ seasons. The seven-time All-Star spent the first nine years of his career with the Portland Trail Blazers.

He's averaged 19.4 points, 8.2 rebounds and 2.0 assists in his career.
