Left-sided player Sweeney, 22, will stay at Huish Park until the end of the season and could make his debut against former club Millwall at the weekend.

Meanwhile, Brittain, also 22, will also spend the remainder of the campaign with the Somerset club.

"We feel it's best for Martin to be out there playing football week in, week out," Town boss Jim Magilton said.

Brittain has already served Yeovil on loan this season, making 10 appearances between late October and early January.

On Sweeney, Glovers manager Russell Slade added: "Peter has good quality with his left foot.

"We've been patient waiting for the right player to come along and I think we've found that. He's skilful and we are enhancing our chances."
