Wests Tigers’ hopes of landing five straight NRL wins have received a significant boost with coach Tim Sheens expecting star centre Chris Lawrence to be fit to face North Queensland at Campbelltown on Sunday.

The injury-prone representative centre sent a scare through the Tigers camp last week when he suffered a hamstring tear in the 24-22 win over the Warriors and was forced from the field in the first half.

But Lawrence, who started at five-eighth against the Warriors, looked in good order as he was put through his paces by medical staff at training on Thursday.

The Tigers coach has named Blake Ayshford at five-eighth while 18-year-old playmaker Curtis Sironen is on an extended bench but he’s expected to drop off if Lawrence is given the all clear.

“I’m hopeful that we’ll get him through but if he’s not right I won’t risk him,” Sheens said.

“I’ve moved him (Lawrence) back to centre so he doesn’t have to work hard on that hamstring by way of efforts during the game.”

Sheens confirmed that a final call on Lawrence and NSW State of Origin hooker Robbie Farah would be made by medical staff on Saturday.

The Tigers mentor praised the performance of Farah in the Blues’ 18-10 loss to Queensland on Wednesday night.

“He’s OK from what I heard,” Sheens said of Farah.

“I think he did play well, particularly when they had some ball and they were going forward … he came up some good plays. I think he’ll be happy with that game.”

The joint venture welcome back tough back-rower Chris Heighington, who hasn’t played since suffering a hand injury in the round six loss to Brisbane on April 6.
