The Clarets have signed former Manchester United goalkeeper Lindegaard until the end of the season.
The Danish stopper, 33, had been training at Sean Dyche's Premier League side this week before putting pen to paper on a deal.
The shoulder injury sustained to Tom Heaton forced the Clarets boss to look for more depth, with Lindegaard arriving.
The Dane had been a free agent since leaving Preston at the end of last season.
On the move, Lindegaard said: “I've had a good week here and I've had a very good impression of the whole club and all the people here.
“It's not hard to fit in nicely here.
“It seems like an honest place and a very hard-working place and I appreciate being a part of it.
“I have seen the first two games Nick has played and he's done very well. I have a lot of respect for that.
“I am here to try and sharpen up the competition in the goalkeepers' department and we'll see what happens down the line.
“I feel good physically and I still want to play. I come here with a good spirit and I have a lot of enthusiasm for getting started.
“I sensed from the first day I came in there was a good atmosphere, that things are in a good place, and it has paid off with a good start to the season."
