Nugent agrees Swans move
The 33-year-old has agreed terms on a deal that will keep him at Vetch Field until the end of the season, having joined the Welsh club on a month's loan last month.
The Swans are delighted to have secured the services of the former Plymouth Argyle, Bristol City and Cardiff City man.
Director of football Brian Flynn told the club's official website: "Everyone has seen how much of an asset he is with his experience and strength so understandably I'm extremely pleased that Kevin has committed himself to us until the end of the season and possibly beyond.
"He is really enjoying himself at Swansea, he's playing first team football again and that was the key."
