Simpson was found guilty of a reckless high tackle for which he was placed on report during the 40-8 defeat by Wakefield on Sunday, but was suspended for just one match at his hearing yesterday. "It's great news because Robbie is a very important member of our team," said the Broncos' coach, Dan Stains.
Dominic Peters will move from the wing to the second row to cover for Simpson's absence against Warrington on Saturday, with Rob Smyth coming back in an effort to prove his fitness for the Challenge Cup final against Leeds a week later.
London are already without Grant Young, Darren Bradstreet and Brett Warton for Wembley because of injuries, while Stains said that he will not select Shaun Edwards if he risks long-term damage to a broken thumb.
"It's a very important football game, to Shaun and everyone here," Stains said. "But his health will outweigh that."
