Collingwood star Dayne Beams has been hospitalised after experiencing an adverse reaction to pain medication.

In a challenging first season back with the Magpies after returning from Brisbane, the 29-year-old has battled ongoing mental health issues along with season-ending hip and shoulder injuries that required surgery.

"Dayne continues to meet the challenges he's been open about with the assistance of his family, medical professionals and Collingwood," the club said in a statement.

"He was admitted to a Melbourne hospital on Wednesday as a part of his ongoing treatment program.

"Dayne and his family thank everyone for respecting his privacy."

The development comes on the eve of the Pies' finals campaign, which will kick off with a qualifying final clash with Geelong at the MCG on Friday night.

After signing a four-year contract with Collingwood, Beams played just nine games this season and the brilliant midfielder's output was significantly hampered by a chronic hip issue that sidelined him in early June after an unusually quiet showing in the shock round 11 loss to Fremantle.
