Luke Walton admits he did meet up with the woman accusing him of sexual assault in a Santa Monica hotel room ... but the Sacramento Kings head coach says she's lying about what went down.
In new legal docs obtained by TMZ Sports ... Walton claims his accuser, Kelli Tennant, was the person who initiated their meet-up, but he is adamant their encounter was "platonic" and nothing sexual even occurred.
In the docs, Walton claims when he was a Warriors coach, Tennant drove to meet him at a hotel the team was staying at while in town to play the Lakers, something she initiated.
