Port Adelaide could lose Jasper Pittard for the start of the AFL premiership season after the influential defender's hamstring injury in Sunday's 28-point trial loss to Richmond.
The Tigers banked consecutive pre-season wins with a comprehensive 0.11.13 (79) to 0.7.9 (51) triumph in tricky winds at Mt Gambier in South Australia's southeast.
Port, without a win from their two pre-season games, were hampered by the loss of Pittard who limped off the ground in the second quarter and didn't return.
The rebounding backman will have scans on Monday after being injured when charging into attack - he stopped short and immediately clutched at his left hamstring.
But Port coach Ken Hinkley dismissed any concern over his brilliant forward Chad Wingard, who hobbled off with a corked thigh in the last term.
"Wingard is fine - just a corky. Jasper is the only injury," Hinkley said.
The Tigers steamrolled Port in the second term, kicking 6.3 to nothing in a game-defining burst.
"We weren't able to change the momentum in the second quarter. We allowed them to dominate for far too long," Hinkley said.
"We know we are nowhere near where we want to be at the moment. We need to stay positive as we work towards how we want to play."
Richmond boasted prolific ball winners in Brandon Ellis, who gathered a game-high 25 disposals, Anthony Miles (24 touches) and Shaun Grigg (20 possessions), while Dustin Martin and captain Trent Cotchin were dominant early.
The Tigers also had dangerous attackers with Sam Lloyd capping his influential game with three goals and key forward Jack Riewoldt slotting two.
Port couldn't find a multiple goalkicker but were well served by onballer Ollie Wines (24 disposals), captain Travis Boak (18 touches), Jared Polec (20 possessions) and Hamish Hartlett (17 disposals).
But the Power ultimately paid for their second-term snooze.
Port led by five points at quarter-time but were overwhelmed in the second term, with Richmond's blitz creating a 27-point advantage for the Tigers at halftime.
Port made some inroads in the third quarter, kicking three goals to one, before the Tigers sealed a convincing win with a solid last term which returned 2.4 to Port's 0.5.
