Error that hurt Logan, unfortunately (3,4)
I believe the answer is:
own goal
'error' is the definition.
(I have seen 'embarrassing error' mean 'own goal' so perhaps 'error' could also mean 'own goal')
'that hurt logan unfortunately' is the wordplay.
'that hurt' becomes 'ow' (I've seen this in other clues).
'unfortunately' indicates anagramming the letters.
'logan' with letters rearranged gives 'ngoal'.
'ow'+'ngoal'='OWN GOAL'
(Other definitions for own goal that I've seen before include "Football score at the wrong end" , "Self-inflicted problem" , "move that backfired?" , "Self-inflicted disadvantage, from soccer" , "Self-inflicted setback" .)
