The Bulldogs are enjoying a major revival – they currently sit second in the NRL table after finishing up as last season’s wooden-spooners.
Idris, 18, is a former world-ranked junior javelin thrower and has scored 8 tries for the Bulldogs so far this season while 23-year-old Roberts has made five test apperances for New Zealand
“For a young kid Jamal has handled his meteoric rise to first grade tremendously,” Bulldogs coach Kevin Moore told AAP.
“He just takes it all in his stride, there’s no doubt he has a long first grade career ahead of him.
“We’d love to see him be a Bulldog for life.”
Roberts meanwhile starred in the Bulldogs’ 44-22 win over Brisbane at the weekend and is approaching his best form for the club since he joined in 2006.
“It’s great to have him (Roberts) on board, this is a good reward for a bloke who has knuckled down and worked hard,” added Moore.
“He’s matured a lot in the past six months and he’s playing great footy.”
