Winners

He may have had a try disallowed and his team may have lost to the Bulldogs but Jason Taumalolo was the Fantasy player of the round, with 188 run metres, eight tackle busts and 39 tackles earning him a season-high 81 points. After four scores in the 30s in the previous month it bumps his season average back above 50 for the season.

Another potential keeper in the back row is Roosters forward Ryan Matterson, who now has four tries for the season including three in the past fortnight and is coming off scores of 71 and 79. There are still some question marks – his top score without a try this year is 43 – but an average of 55 and a break even of 20 makes him a tempting option at $741,000.

Tigers halfback Luke Brooks is also coming off back-to-back scores in the 70s after he and Benji Marshall (71) carved up the Sea Eagles on Sunday, South Sydney trio Damien Cook (73), John Sutton (72) and Angus Crichton (66) were excellent in the Rabbitohs' win over the Roosters on Thursday while cash cows Raymond Faitala-Mariner (71 points, +$47k), James Maloney (67 points, +$84k), Jaydn Su'A (60 points, +$58k) and Jamayne Isaako (54 points, +$40k) all provided points and cash for their Fantasy owners.

And stay tuned for dual position updates for several players this week, with Sam Burgess (FRF), Adam Blair (2RF), James Fisher-Harris (FRF), Trent Merrin (FRF), Hymel Hunt (WFB), Sia Soliola (FRF), Aidan Tolman (2RF), Nathan Ross (CTR), Asipele Fine (2RF), Brad Parker (CTR) and Bunty Afoa (FRF) among those set to become available in a second position in Fantasy. More updates will come after round 12.

Losers

Just as it seemed star Sharks duo Andrew Fifita (41) and Paul Gallen (8) had become good value buys both of them were struck down by injuries, along with teammates Wade Graham and Luke Lewis. The good news is Fifita's isn't as bad as first feared – he'll be out for weeks with a PCL injury rather than for the season with an ACL – and Gallen and Graham should also return by round 11.

Titans Fantasy gun Jai Arrow (38) was down on previous weeks after suffering back spasms in their loss to the Panthers, while Johnathan Thurston (18) had another disappointing game in the Cowboys' loss to Canterbury.

Popular cash cows Richie Kennar (14), Tevita Pangai jnr (19), Robbie Rochow (20) and Slade Griffin (29) may have hit their peak prices after quiet performances on the weekend. Now's the time to start cashing those guys in and bringing in a big gun or two to strengthen your starting side.
