However, in-form winger Ryan Shaw - who has scored four tries in seven games since joining from Bradford Bulls - will miss the rest of the season after rupturing an anterior cruciate ligament in his knee at Wigan on Easter Monday.
That makes the return to fitness of other key players all the more crucial for Rovers, who have still only one win to their name so far.
Captain Campese strained a hamstring against Huddersfield Giants earlier this month just minutes into the stand-off’s return from his own knee reconstruction that sidelined him since last June.
Having been kept out due to ankle surgery, hooker Lunt also played his first game of the season in the defeat at Huddersfield only to strain his calf and miss the next three games.
However, both return as Rovers - who should have defeated Hull FC on Good Friday and showed spirit with a youthful side at Wigan - venture to Headingley looking to add further misery to struggling champions Leeds.
“Of course, Shaun and Terry were bitterly disappointed with their injuries at Huddersfield,” said Webster, who also confirmed former Rhinos second-row Chris Clarkson is fit to reclaim his place in the 17.
“They’re professionals, want to win and help us progress.
“No player goes out thinking about getting hurt, but I’m sure they’re looking forward to facing Leeds.
“Both Terry and Shaun are going to play.
“Terry will start but I’m not sure on Shaun. We have got a couple with a sickness bug so we’re a little bit up in the air.”
