Millwall have agreed the signing of defender Danny Shittu on a three-month arrangement.
The 30-year-old centre-half, who worked with Lions boss Kenny Jackett at QPR, is a free agent after leaving Bolton in the summer.
"The move ticks all the right boxes for me," he told the club's official website.
"I'm excited to be coming here and I hope to help Millwall push up the table.
"I know about the club from friends who are supporters and everything I've heard has been positive."
