PORT Adelaide has recorded a hard-fought 16-point victory over Carlton as the Blues continued to tantalise their fans at Adelaide Oval on Saturday.

The 13.10 (88) to 11.6 (72) encounter was marred by potentially serious injuries to Blues star Charlie Curnow and Power pair Jack Watts and Karl Amon.

Curnow left the field with a minute remaining in the first quarter, the forward clutching at his left knee after jostling with Port defender Dan Houston on the wing.

The 22-year-old jogged along the boundary line during the second quarter but eventually returned to the bench where he remained for the rest of the match.

Watts was stretchered off in the final term after the 28-year-old's right ankle was caught under Dale Thomas as the Blues veteran tackled him to the ground.

Karl Amon spent the most of the match on the sidelines after suffering a first-quarter knee injury.

Power ruckman Scott Lycett was best on ground collecting 25 possessions (17 contested), 34 hitouts and 10 clearances.

Tom Rockliff finished with 37 possessions and 12 clearances, Steven Motlop booted three goals (including two in the fourth quarter), Brad Ebert kicked three as well while Travis Boak continued his midfield resurgence with 33 disposals.

Patrick Cripps was dominant for the Blues while Paddy Dow and Sam Petrevski-Seton were busy as well.

After a free-flowing end-to-end opening, showers swept over Adelaide Oval at the start of the second half and it was Carlton which enjoyed the change in weather conditions.

They claimed the lead for a few minutes in the third term.

But the Power stood up in the big moments in the fourth quarter, with first-year players Zak Butters and Xavier Duursma setting up Motlop's goals to give the home side some breathing space.

It wasn't a big outing for Justin Westhoff in his 250th but it's the first time the Power have saluted one of his milestones – the team lost in his 50th, 100th, 150th and 200th matches.
