What is Greg Haugen's record?

40–10–1 in boxing. That is the aggregate stated in the English Wikipedia infobox; the results table on the same article lists 51 bouts individually.

How many of Greg Haugen's bouts have no date?

1 of 51. The source lists them without a date this site can read, so they are printed with no year, sorted last, and drawn past the double rule in the record line rather than placed in the chronology. No year has been inferred for any of them.

Does a no contest change a record here?

No. A no contest is not a win, a loss or a draw, and it is never folded into one. It is counted and printed separately, so a 20–0 record with two no contests is shown as exactly that rather than as 22–0 or as 20–0 with the no contests dropped. The same applies to a bout overturned after the fact where the source records the change.

What happens when sources disagree about a fight?

This site publishes one source — the fighter's English Wikipedia article, read on the date printed under every table — and it does not silently reconcile that against anyone else's database. Where the article's own infobox total and its own results table disagree, both are shown and the page says which one each figure came from. Nothing is averaged, and no field is filled in from a second source to make a total balance.

How this record is compiled

Measurements come from the fighter's English Wikipedia infobox; the bout list is parsed from the results table on the same article, read on 2026-07-07. Boxing tables are read by header name and MMA records by the fixed column order of the MMA record template — two different parsers, because reading MMA rows as a boxing table returns a fighter's boxing record in place of their real one.
A bout enters the ledger with whatever fields the source states: result, opponent, method, round, year. Any field the source leaves empty stays empty here. A date that cannot be established is left blank rather than inferred, and the bout is still counted.
A no contest is counted and printed as a no contest. It is never folded into the wins, the losses or the draws, and it never disappears to make a total balance.
Where the article's infobox total disagrees with its own results table, both figures are published and each is labelled with where it came from. Nothing is averaged and nothing is reconciled against a second database.
Percentiles rank this fighter among the 130 welterweight boxing fighters in the dataset — the most specific group of at least 30 that this fighter belongs to.

What this record does and does not say

What is Greg Haugen's record?: 40–10–1 in boxing. That is the aggregate stated in the English Wikipedia infobox; the results table on the same article lists 51 bouts individually.
How many of Greg Haugen's bouts have no date?: 1 of 51. The source lists them without a date this site can read, so they are printed with no year, sorted last, and drawn past the double rule in the record line rather than placed in the chronology. No year has been inferred for any of them.
