Newcastle United have signed German keeper Loris Karius on an initial contract until January.
The 29-year-old was a free agent after leaving Liverpool in the summer and there is an option to extend the deal until the end of the season.
Karius has arrived after back-up keeper Karl Darlow suffered an ankle injury.
"I felt it was the right project for me and I'm excited to work with the coaches and my new team-mates," he said.
Newcastle lost fellow stopper Martin Dubravka during the summer when he joined Manchester United on a season-long loan, while Nick Pope joined from Burnley.
