Sydney coach John Longmire has confirmed big man Kurt Tippett has avoided a serious injury after injuring his ankle on Friday night.

Tippett landed awkwardly after taking a mark in the first quarter and took no further part in the game, as the Bulldogs enjoyed a 23-point win over the Swans.

Despite looking like a nasty injury at the time, Tippett will most likely only miss one match, this week's clash with Collingwood at the SCG.

"He's walking around on it OK, which is a good sign, but this early in the week he's unlikely to play," Longmire said on Monday.

"We think he'd be almost a certainty to play against West Coast (in round four).

"We're lucky enough that we've got two boys in the reserves who can come in and play that position for us if we need them too.

"We're comfortable in bringing either one of them into the team, and I'm on the record as saying it's very important to have a quality group of ruckmen, and we're fortunate that we do."

Sydney could also be without midfielder Zak Jones against Collingwood, after he was reported for a late bump on Western Bulldogs forward, Travis Cloke.
