Luke Lewis has agreed to a one-year contract extension which will keep the veteran NRL back-rower at Cronulla until the end of 2017.

Off-contract at the end of this year, the 33-year-old has agreed to terms but is yet to put pen to paper.

Lewis reportedly attracted interest from South Sydney but has elected to stay put in the Shire in what shapes as his 17th and final season in the top flight.

"It's been good to get the decision out of the way," Lewis said on Wednesday.
