Priest given right to plug team’s sovereign remedies (7)
I believe the answer is:
elixirs
'sovereign remedies' is the definition.
(sovereign remedy can mean a cure-all)
'priest given right to plug team's' is the wordplay.
'priest' becomes 'eli' (I've seen this before**).
'given' says to put letters next to each other.
'right' becomes 'r' (common abbreviation).
'to plug' indicates putting letters inside (to plug can mean to block a gap within something).
'team's' becomes 'xis' (eleven, a football team).
'r' going within 'xis' is 'xirs'.
'eli'+'xirs'='ELIXIRS'
(Other definitions for elixirs that I've seen before include "Magic potions" , "Substances believed to cure all ills" , "Magical potions" , "Panaceas" , "Cure-alls" .)
