Sal D'Amato was more active than all other judges at UFC events in 2017, as he returned to the top of the list of the year's busiest UFC judges. D'Amato previously topped the list in 2013 and 2015.

Jeff Mullen slotted in at the second position, up three spots from the previous year.

Last year's busiest judge, Derek Cleary, was once again a frequent presence at major MMA events in 2017. But a small decrease in total UFC scorecards saw him drop to the number three position.

New to the top 10 list in 2017 were American east coast judges Dave Tirelli and Eric Colón.

Dropping off the list in 2017 were Las Vegas judges Glenn Trowbridge and Junichiro Kamijo. Trowbridge had the biggest drop-off, only submitting scorecards in 13 UFC decisions, down from 39 in 2016.
