Adam Herczeg
The independent Key Match Incidents panel has reviewed 1 of those matches and confirmed 0 errors in them. Everything below is a count: RefCard publishes errors, not an accuracy percentage, because no source publishes the denominator such a figure would need.
Season by season
| Season | Matches | Fouls/game | Yellows/game | Reds/game | Penalties | Confirmed errors |
|---|---|---|---|---|---|---|
| 2026-27 | 1 | 22.0 | 5.00 | 0.00 | 0 | 0 |
Confirmed errors are only available from 2023-24, when the Key Match Incidents panel began. Earlier seasons show the disciplinary record only.
Cards and fouls
Not enough Premier League matches to publish a career card rate.
Added time
No second-half added-time record held for this referee yet.
Club by club
Every club refereed at least three times, with that club's own record in those matches and the cards it took.
| Club | Matches | W–D–L | Yellows | Per game |
|---|
The W–D–L is the club's. Nothing here is evidence of bias — a difference this size is what chance looks like. See how that was measured.
Panel review
The Key Match Incidents panel has not published a review of any decision from Adam Herczeg’s 1 match in 2026-27 — and it reviews only a selected set, so that says nothing about whether those decisions were right.
