Retirement isn’t forever.

Michael Jordan came back. Brett Favre couldn’t make up his mind. George Foreman and Michael Phelps came back after retiring.

It appears that list might grow one name longer, according to ESPN.

Ray Allen, one of the best three-point shooters in NBA history, is considering making a comeback with the Golden State Warriors or the Cleveland Cavaliers. ESPN sources say Allen “is intrigued by the possibility of playing for another championship.”

Allen reportedly would also consider playing for the San Antonio Spurs or the Los Angeles Clippers.

ESPN sources say the Warriors aren’t sure if they want to look into signing Allen. The Warriors acquired the biggest free agent on the market in Kevin Durant, and, after agreeing to trade Andrew Bogut to the Mavericks, Golden State picked up Zaza Pachulia, as well.

Allen will turn 41 this month, meaning if he were to return, he’d be the oldest active player in the NBA. Only nine players in the history of the NBA or its predecessor, the BAA, have played past their 41st birthdays.

Allen’s last season was the 2013-14 campaign. He averaged 9.6 points and 2.8 rebounds per game that season playing for the Miami Heat.
