Leeds Rhinos have suffered a major blow with the news that Kevin Sinfield is expected to be out of action for up to six weeks with a thumb injury that requires an operation.
The Rhinos revealed the England captain suffered the problem on international duty during the first half of the win over the Exiles on Friday night.
Despite the setback, Sinfield was initially named in Leeds' squad for tonight's clash with Widnes Vikings, but he will now stand down.
"England captain Kevin Sinfield will have an operation on his thumb on Tuesday after scans revealed the worst case scenario following his injury suffered in the first half of the International Origin game on Friday," said a statement on Leeds' website.
"Sinfield saw specialists on Monday morning to confirm the injury and has been immediately booked in for an operation on Tuesday and is expected to be out of action for up to six weeks."
It is the latest injury blow for the reigning Super League champions, who are already without a host of players but could move into fourth in the standings with victory over the Vikings tonight.
Sinfield joins Carl Ablett, Ryan Bailey (both thumb), Brett Delaney, Joe Vickery (both knee), Stevie Ward (shoulder), Danny McGuire (leg) Liam Hood and Kallum Watkins (both ankle) on the treatment table.
