Leeds Rhinos could be without Harry Newman for up to six weeks after the club's worst fears over his hamstring injury were realised.
Newman suffered a recurrence of the injury he sustained in pre-season during last week's game against Wakefield Trinity, his first Super League appearance of the season.
It means the centre is now set for a prolonged absence of between four and six weeks, with Rhinos head coach Richard Agar insisting they will also have to be 'ultra-careful' over how they manage the injury moving forwards.
