London Broncos are able to welcome back Michael Witt for Saturday's clash with Leeds at the Twickenham Stoop.
Australian half-back Witt sustained a shoulder injury in the away loss to Wakefield back on June 3, forcing him to miss the last two outings.
However, Witt is fit to return for the match against the reigning Stobart Super League champions along with Jamie O'Callaghan, who is available again after sitting out last week's defeat to Huddersfield due to illness.
Shane Rodney and Chris Melling are out due to respective neck injuries while Liam Colbon is recovering from a shoulder reconstruction and Matt Cook is sidelined with ligament damage.
Karl Temata (hamstring) and Jason Golden (knee) are both sidelined for the hosts, so Olsi Krasniqi is recalled to the 19-man squad.
"It's good to have Jamie O'Callaghan and Michael Witt back after injury and illness," Broncos head coach Rob Powell said on the club's official website.
"We go in to the game following a win in our last home outing and having competed for 60 minutes at Huddersfield. We therefore want to put in a good performance."
Leeds, meanwhile, are without a number of first-team regulars for their trip to the capital.
Brett Delaney remains at home due to a groin strain and Jamie Peacock, who this week announced his retirement from international action, is still recovering from a minor knee problem.
Another absentee is Brent Webb (knee), so Zak Hardaker looks set to continue in his new role at full-back.
Rhinos head coach Brian McDermott has also drafted in Lee Smith as his side look to prove they are back on form with a third straight league win.
Leeds lost on their last visit to the Stoop, going down 32-22 a week before they played in the Challenge Cup final against Wigan at Wembley.
"London will be desperate for a win," McDermott said. "We cannot overlook where they are in their season.
"They have some big game players and have scored a lot of points this year, even if results have not gone their way.
"Last season we came down here on a horrible day, both in terms of the weather and our performance, and that is something I am sure our players will not have forgotten and will want to make amends for."
