The Broncos sit in seventh place on the ladder, two points behind fourth-placed Dewsbury. With matches against competition heavyweights Bradford and Leigh in the next fortnight, the Broncos are in the market for reinforcements.
The unexpected return of Brad Dwyer to Warrington last week has left London light in the number 9 position and head coach Andrew Henderson came out of retirement to help the Broncos defeat Sheffield 46-6 at the Summer Bash in Blackpool.
Henderson is set to keep the boots on until a new hooker has been signed.
“We need to strengthen our middle,” he said.
The Broncos are close to announcing the capture of a front-rower with Super League experience.
London remain in the hunt for a top four finish and a spot in the middle eights later this year.
Henderson said his side’s big win over the Eagles has kept the Bronco’s “season alive”.
“We’re two points off fourth,” he said.
“We’re starting to show some signs on improvement. We’ve got a hell of a lot of work to do. It’s a big challenge for us.”
