The 30-year-old Queenslander began his career with the Brisbane Broncos in 2000 and quickly established himself as one of the game’s feared enforcers.
His 12 memorable performances for Queensland led to a Test appearance for the Kangaroos in 2008, and he was selected in the Indigenous All Stars team which took out the inaugural Rugby League All Stars match in 2010.
Webb joined the Eels from the North Queensland Cowboys at the beginning of this year and has appeared for the Eels in five matches this season.
Eels coach Stephen Kearney said:
“We’ve been lucky to have a player of Carl’s experience in our squad,” Kearney said.
“He has had a terrific career – his performances over the years, particularly at representative level, are ones I won’t forget.
“Carl’s had a tough time with injuries this year but although he hasn’t spent a lot of time on the field, he’s been invaluable when it comes to helping out our younger forwards.”
“We want to wish him all the best for life after footy and congratulate him on everything he’s achieved in his career.”
