Burnley midfielder Marvin Bartley has joined Leyton Orient on an emergency loan deal.
The 27-year-old has linked up with the League One side for a 28-day period ahead of their opening league match against Carlisle United this weekend.
Burnley boss Sean Dyche told the club's official website: "Marvin has had a disjointed pre-season after picking up a hamstring injury, so he is around three weeks behind everyone else.
"He really needs to be playing competitive games, so the move will hopefully give him that opportunity."
Bartley has made 72 appearances for the Clarets since moving from Bournemouth in 2011.
