Wollongong Lions' clash with Bomaderry was abandoned before half-time after a Tigers player suffered a neck injury at North Dalton Park.
Tyler Dunstan was hurt while contesting the ball, with a delay of more than 30 minutes as he was treated by ambulance officers.
It is understood Dunstan has been cleared of any serious injury and has regained feeling in his arms and legs.
Aided with a stiff breeze at their backs, the Lions had kicked six unanswered goals in the opening term, but Bomaderry had roared back into the contest in the second quarter to be within 19 points when the incident happened.
The Lions remain the league's only unbeaten team, but won't play for another three weeks, because of next Saturday's representative weekend where South Coast take on Black Diamond and a bye the following round.
And the round two game against Kiama is also unlikely to be replayed, after it was initially postponed due to the sudden passing of Power life member Darren Williams.

The premiers kicked 4.2 to four points in the final term at Bonaira Oval.
In the other game, Figtree continued Shellharbour's miserable start to the season, running out 21.13 (139) to 5.2 (32) winners, including a seven-goal onslaught in the last term.
Coached by Kiama premiership coach Rod Richards, South Coast take on the Black Diamond League at West Newcastle on Saturday.

Cailah Bell kicked four goals and Shellee Gibson three, while Tyler Finn and captain Talarah Bull, sister of Sydney Swans rookie prospect James Bell, were among their best.
Elsewhere, Wollongong Lions overpowered their grand final conquerors Bomaderry by 21 points and Wollongong Bulldogs defeated Kiama Power by 49 points.
