Former NBA player Darius Morris -- a Lakers second-round pick in 2011 -- was arrested last month after a woman claimed he brutally attacked her ... but now the woman is insisting she made the whole thing up.
A spokesperson for the NYPD tells TMZ Sports ... on April 18, a woman told officers the 29-year-old pro basketball player beat her up during an altercation at a Manhattan-area home.
The woman told cops she had left the residence, and asked Morris to leave by the time she got back. But, she says when she returned, Darius was still there -- and he exploded on her.
