The Tigers, hammered 42-10 by Newcastle in the opening round, rebounded with a five tries to three win, prop Aaron Woods scoring a double for the home side as he continued his recovery from minor knee surgery.
He might be forced to play without engine room buddy Galloway for a while, however, after the NSW Origin prop went straight up the tunnel just moments after halftime clutching his arm.
The Panthers also lost a key player to a similar injury, with Lachlan Coote forced off after only 11 minutes to spark a major reshuffle with skipper Kevin Kingston forced to fill in at five-eighth.
While the Tigers bagged the points, coach Michael Potter still has plenty of work to do, particularly in defence with his side conceding plenty of metres up the middle.
Sika Manu scored the first of two tries after five minutes when a wicked bounce from a David Simmons kick gave the visitors the perfect start.
A Robbie Farah quick tap from a penalty led to a simple Benji Marshall four-pointer, the Kiwi regaining some of his swagger with a flick pass that almost led to a spectacular try for winger Marika Koroibete.
Jacob Miller stepped and weaved his way over for a 12-6 lead, Woods sandwiching his double around a clever Simmons effort just inside the corner post.
Koroibete put the result beyond doubt when he was last man standing after a Marshall grubber, the Tigers also seeing Chris Lawrence limp off late in the game.
