Contacted regulars of team and suffered (7)
I believe the answer is:
emailed
'contacted' is the definition.
(contacted using email)
'regulars of team and suffered' is the wordplay.
'regulars of' means one should take alternating letters (I've seen 'regular' mean this).
'and' says to put letters next to each other.
'suffered' becomes 'ailed' (ailing is a kind of suffering).
The alternate letters of 'team' are 'em'.
'em'+'ailed'='EMAILED'
(Other definitions for emailed that I've seen before include "Contacted" , "Communicated with" .)
