Oldham were left to rue a controversial goal-line decision by referee Andy D'Urso in a stalemate at Bournemouth.
Marc Pugh wasted an early Cherries chance when he side-footed debutant Charlie Daniels' left-wing cross wide.
In first-half stoppage time, Oldham striker Robbie Simpson's shot was blocked by Steve Cook but the visitors insisted the ball had crossed the line.
Substitute Charlie Sheringham hit the bar with a fierce shot in injury time as the hosts threatened a late winner.
VIEWS FROM THE DRESSING ROOM
Bournemouth manager Lee Bradbury told BBC Radio Solent:
"We have got another gear but they made it difficult for us. They are organised and hard working. We can play better but it's a good point.
"() He came into training and settled straight away. He knew a couple of the lads already and that's helped him.
"(On the assistant manager situation) It will be resolved this week. The transfer deadline day kept us occupied and set us back a bit."
Oldham Athletic manager Paul Dickov told BBC Radio Manchester:
"I'm delighted to get the clean sheet and defensively I thought we were fantastic.
"The players are convinced it was a yard over the line and I don't think it should be too hard for the officials to get it right.
"It's disappointing but lets not take anything away as this is a tough place to come."
