Johnny Walker vs Thiago Santos — Fight recap

Thiago Santos defeated Johnny Walker via unanimous decision after five rounds on October 2, 2021, with referee Herb Dean officiating. Santos landed 44 significant strikes at 41% accuracy compared to Walker's 48 strikes at 36%, demonstrating superior precision despite lower volume.

Walker attempted 130 total strikes to Santos's 105, relying heavily on leg kicks with 32 landed, yet failed to convert that activity into judges' favor across all three scorecards. Neither fighter secured takedowns or accumulated control time, making this a pure striking affair where Santos's cleaner, more efficient combinations—particularly 16 body strikes to Walker's nine—proved decisive.

The loss marked a significant setback for Walker's light heavyweight momentum and suggested Santos remained a formidable gatekeeper in the division despite ongoing injury concerns.
