Adam MacDougall out for the season

South Sydney back Adam MacDougall has been ruled out for the season after he snapped his Achilles tendon at Melbourne's Olympic Park tonight.

The news couldn't have come at a worse time for Souths fans who are still reeling from their side's 50-4 loss to the Storm.

MacDougall, 29, fell awkwardly in a tackle in the 78th minute and his fears were confirmed immediately after the match.

The former Knights winger has a history of injuries and this latest disappointment will be hard to come back from.

"Adam's out for the season ? he's pretty upset," Souths coach Paul Langmack said.

"It just went in the last tackle, moved forward and fell over right at the end."
