According to Yahoo! Sports, center Jermaine O’Neal is poised to accept a two-year offer to join the Celtics. The 6-foot-11 O’Neal is believed to have been offered the $5.8 million mid-level exception.

A 13-year veteran, the 31-year-old O’Neal played the last two years in Miami. He averaged 13.6 points and 6.9 rebounds in 70 games last season after three injury-plagued seasons prior. He also reportedly has been considering offers from the Nuggets and Mavericks.
