The Australian has damaged a hamstring, and is set for a four-week lay-off.
“A few words spring to mind but ‘frustrated’ is the one I’ll go with to sum up how I’m feeling at the moment,” Campese wrote in his Yorkshire Evening Post blog.
“After working so hard to get back on the field against Huddersfield on Sunday, there were no signs that anything was going to go wrong in the game. I was actually feeling good skill and fitness wise and I felt I slotted back in reasonably well.
“Then in the second half I just landed awkwardly after one of my kicks and I’ve damaged my hamstring.
“The docs are saying I’ll be out for about four weeks and I’m gutted to be missing the Easter period as I wanted to be around to help the team get back on track.
“It means I’ll miss another home derby against Hull FC too, which I was looking forward to experiencing.
“It just about sums up the luck the club is having at the minute.”
The Italian international is relieved, though, that the issue is not yet another knee injury in a career which has been plagued by them.
“I am at least glad it’s my ‘hammy’ and not my knee again,” he added.
“So I’ve got to knuckle down now, put all that disappointment aside and focus on getting my rehab right.”
