BYRON Webster said it was "a very easy decision" to put pen to paper on a new deal with Millwall.
Webster, 29, has signed a contract that will keep him at the club until the summer of 2018.
Webster scored as Neil Harris' side defeated Oldham 3-0 on Saturday in their opening League One fixture this season.
After Millwall confirmed the deal, Webster, speaking on the club's official website, said: "I'm really pleased. It was a very easy decision for me to make because I'm really enjoying my time here at Millwall.
"There is a great group of lads here and I'm looking forward to playing a part in what we all hope will be a successful season for the club."
The Yorkshire-born defender made 50 appearances last season, scoring six goals, and became one of the most consistent players in Harris' side as they fell just short of reaching the Championship.
Webster joined Millwall from Yeovil Town in July 2014 but had a difficult first season and spent the latter part of the campaign on loan at his former club.
But the former Northampton and Doncaster player has since nailed down his first-team place and his appearance against the Latics was his 66th for Millwall.
