Preston have completed the loan signings of midfielder Nathan Doyle from Barnsley and defender Jamie McCombe from Huddersfield.
The pair will remain at Deepdale until 2 January.
Doyle, 24, who has made 10 appearances for the Tykes this season, has had spells with Derby, Notts County and Hull City.
McCombe, 28, has not featured for the Terriers in the league since being sent off against Leyton Orient in September.
Both players will go straight in to the Preston squad for Saturday's visit to Bury in League One.
