Maxwell hurt his wrist in last Sunday's match against Carlton at the MCG and saw a surgeon today. The 29 year-old premiership skipper requires surgery and, according to Collingwood's director of football, Geoff Walsh, is unlikely to be available again before late May.
"Unfortunately, Nick is looking at a spell," Walsh said.

"His wrist was sore and the pain wasn't easing. He's got a crack that requires surgery that, at this stage, is likely to keep him out for six weeks and possibly a little longer.
"I'm sure that Nick, being the professional he is, will do everything he possibly can to be back as early as possible."
