The 26-year-old has been away from the game for 18 months, but is looking forward to getting back into action with Wests.
“For me, it’s so exciting as there are a lot of up-and-coming young players here,” said Idris.
“The average age is really young, and they’re only going to get better and more experienced. If they do that together, then they’re going to gel well as a team and that’s really exciting.
“I’ve learned a lot over the last year, and the biggest thing was that I was playing rugby league for others. This time, I’m playing rugby league for myself.
“There’s no better way to get back into it then to get stuck into training, and I’m improving a lot every week. I’m just hoping to do it now week in and week out.
“I can’t wait to meet all the new fans and members of Wests Tigers.
“This club has a great history and supporter base, and I can’t wait to meet and get to know so many more fans.”
Wests Tigers head coach Jason Taylor is delighted that the player has re-joined the club.
“We’re really looking forward to having Jamal join us ahead of the 2017 season,” he said.
“He brings a lot of size and strength to our outside backs which is something that we identified that needed to be improved on for the coming year.
“Jamal has played the game at the highest level and comes to Wests Tigers with a lot to prove.
“He’s been working hard over the last couple of weeks to ensure that he’s ready for the start of pre-season and he’s incredibly motivated to get back into the game and we’re really happy that he’s decided to do it with us.”
