Fears that rookie Benji Marshall may miss the rest of the National Rugby League season have been allayed - but that's where the good news ended for Wests Tigers coach Tim Sheens.

The exciting utility - described as the "next big thing" by NRL CEO David Gallop at the 2004 season launch - was ruled out for up to six weeks with a dislocated shoulder in another injury blow to the Tigers.

Scans revealed Marshall did not need surgery but must still undergo six weeks of "intensive rehabilitation".

"I'm disappointed I'll miss part of the season, but I believe Wests Tigers has the depth to test the strong sides and this weekend's game with the Dragons should be a strong contest", said Marshall.

Sheens hoped to have Marshall back for their round 10 clash with the Canberra Raiders at Campbelltown Stadium in May.

It was the last thing Sheens needed after already overlooking an injury list that included Michael Buettner (knee), Anthony Laffranchi (knee), Todd Payten (broken arm), Pat Richards (ankle) and skipper Darren Senter (broken arm).

"We will certainly miss him," Sheens said.

Marshall was lost in the first half of Wests' historic win over the NQ Cowboys in Townsville on Saturday.

It was the first time any part of the joint venture - the Tigers, Balmain or Wests - had beaten NQ in Townsville.

"We were buoyed by the win, to beat them with 16 men up there was a bonus - we haven't been able to beat them up there before with 17 men," Sheens said.
