Self-help guru Tony Robbins is promising a triumphant return for disgraced UFC star Jon Jones ... saying he knows Bones will come back good as new ... 'cause he's a client.
TMZ Sports got the star of the new documentary "I Am Not Your Guru" out in NYC and asked him about the state of Jones' career after a failed drug test prompted his removal from the card at UFC 200.
Jones is now facing a potentially lengthy suspension from USADA, and the whole MMA world wants to know ... can his career recover?
Check out the clip -- Robbins is absolutely sure Bones can bounce back, saying Jones knows he's got what it takes to get back to the top.
