Widnes pair Macgraff Leuluai and Owen Buckley have both taken pay cuts to sign new deals with the club.
Leuluai, 29, has signed a one-year extension and will enter his 10th season with the club, after originally signing from Leigh in 2011.
In that time, he has amassed over 150 appearances in both the Championship and Super League, scoring 13 tries.
“I’ve spent a long period of my life here in Widnes and it has become a second home for me, so there was no doubt in my mind that I would be staying here,” he said.
“After what we went through as a group and a club last season, we’re determined to make 2020 a great year and I’m looking forward to helping the club rebuild.”
Buckley has signed a new two-year deal that will see him remain a Viking until the end of the 2021 season.
The 20-year-old only made his debut last season but has earned a reputation as a natural try-scorer, grabbing 10 in 15 games.
“I’ve been a fan and sat in the stands watching Widnes over the years, so to be able to run out and play for my home town club is still a dream.
“The chance to work with one of the best coaches in the world in Tim Sheens is something me and the rest of the lads should be excited about, and I can’t wait to get going with the boys in pre-season again.”
