For their part, the Warriors might be 15th but they are only four points adrift of the top eight.
Cleary has named an unchanged lineup while the Warriors welcome back prop Sam Rapira, who is still battling a troublesome hand injury but is expected to play. Centre Dane Nielsen (ribs) was thought to be a chance but is said to be still a week away, as is fullback Kevin Locke (back).
Second-rower Feleti Mateo, who penned a new three-year deal yesterday, will play his 150th NRL game and 62 consecutive match - he hasn't missed one since joining the Warriors in 2011.
The Panthers have won 15 of the 30 matches between the two sides, with one draw, but the Warriors have won four of the past five. That looks quite good, but countering that is the fact they have lost their last eight matches in Australia.
