After looking at batting and bowling fails in all three formats, we turn our attention to those who failed to make any fielding dismissal in their careers.
Here we have these players arranged in order of innings fielded:
Amir Hamza of Afghanistan leads by a large margin over the better known Rangana Herath, currently the Sri Lankan Test captain and the only current Test player who made his debut in the 1990s.
Amir Hamza is an useful bowler but not much of a batsman either. But he is a regular for ODIs and T20Is at the moment.
A number of other somewhat well-known international players appear here, including some Test players.
You can see that the results would be virtually the same if you arrange them in order of matches played.
Now we look at wicket-keepers who have failed to dismiss anyone:
A number of Test and ODI players here, who have at least made some dismissals at those levels. The leader here is Regis Chakabva (9 Tests, 9 dismissals) followed by Carlton Baugh (no less than 21 Tests, 43 catches and 5 stumpings). NV Ojha has played one Test and one ODI and has made dismissals in both.
Finally, we look at those who never fielded in their T20I career:
Nothing profound here. These two players from Netherlands were involved in a washed-out game against Ireland in 2008. As the toss was made, ICC rules state that this match counts in their career records. (Statisticians may disagree; as some disregard matches involving the ICC XI and their like, perhaps these matches should also be disregarded).
While Mol did play several ODIs, Schoonheim did not play for his country on any other occasion.
