Joseph Mills has extended his emergency loan at Oldham Athletic until October 13.
The Clarets defender joined the Latics on emergency loan in August and has played in all five games while at Boundary Park.
Mills, 23, initially joined Burnley on a season-long loan from Reading in the summer of 2012.
In his first season at Turf Moor he made 12 appearances before the loan automatically became a permanent two-year deal this summer.
