The Tigers have confirmed Tim Simona will be rested for this week’s clash with the Warriors in Wellington after failing a final cognitive test during the week.
Simona sustained concussion in the second half of the club’s 25-16 win over Souths, and had earlier turned in an impressive two try performance before coming from the field in the 59th minute.
Representative centre Chris Lawrence will replace Simona out wide as he returns from the hamstring injury that had ruled him out of the Round 3 fixture.
Tigers captain and incumbent NSW hooker Robbie Farah will be given until 24 hours before the match to overcome a calf strain that has seen him miss training earlier in the week.
