Rogers confirmed speculation the Titans had registered his playing contract with the NRL just days before the June 30 deadline.
The 35-year-old, who retired at the end of last season, said he badly wanted to help the struggling side, which is languishing at the foot of the competition ladder.
“Why? I love the team and I hate seeing them hurting and the fans hurting I know they’re better than that and I want to help,” Rogers, a veteran of 199 NRL games, said via his Twitter account.
“It’s not about me being a saviour or any of that rubbish, some of my best mates are there and as a huge Titan fan, they asked and I obliged.
“It will be just the remainder of this season.”
Rogers could return for the Titans as soon as their clash with the Warriors in Auckland on Friday week.
