Star Collingwood defender Jeremy Howe has undergone a minor operation to drain a corked thigh, according to a report by Channel Seven's Mark Stevens.

Howe had previously missed four games in the back end of the 2018 home-and-away season with a bad cork that required draining when he experienced internal bleeding in the leg.

The procedure comes after Howe suffered a knock to that same thigh in a collision with Darcy Moore at Magpies training last week, resulting in further bleeding in the thigh.

The surgery is an attempt to cauterise the part of the blood vessels in Howe’s leg causing the bleeding.

Collingwood believe that Howe’s procedure will only keep him from the field for a brief period and that the procedure will prevent a recurrence of the condition in the future.

Meanwhile, most other Magpies are tracking well in their preseason training.

Dayne Beams, Adam Treloar, Jamie Elliot and Daniel Wells are all in full training, after having their offseason training loads managed.

Collingwood will ramp up their preseason preparations when they host Melbourne for a closed-doors practice match at the Holden Centre on the morning of Friday February 22.
