Collingwood ruckman Jarrod Witts will definitely be replaced by Brodie Grundy in the team to play Richmond after it emerged the ruckman has been forced out after splitting the webbing in his hand.

Witts split the webbing in the second half against the Swans and needed stitches to repair the tear. He returned to the ground on Saturday night but will need to miss this week to allow the split hand to heal.

Witts would have been under pressure to hold his spot in the side in any event after a poor game against Swans pair Kurt Tippett and Callum Sinclair.

While the split webbing was an explanation for a poor second half that was no excuse for his form in the first half, in which he was able to have no impact on the contest.

"We certainly don't want him to play this week, he needs to let the wound heal," Collingwood football manager Neil Balme said.

Grundy, who was overlooked for round one because Witts' pre-season form had been better, will come into the side to take on the Tigers who have their own concerns in the ruck. First choice ruck Ivan Maric missed the opening round with a back injury, replaced by Shaun Hampson.

The Witts injury will mean that with Swan also out with a broken foot and Steele Sidebottom sidelined through suspension, the Magpies will make at least three changes. Ben Reid's return to match fitness through the VFL where he was best on ground at the weekend, means he will also certainly come into the side. The Magpies are likely to make at least four changes, if not more.

James Aish is expected to come in as a replacement for Sidebottom while Jeremy Howe is a strong chance to replace Swan in the forward line.

Important running player Travis Varcoe, one of Collingwood's best players sine coming across from Geelong, is likely to miss at least one more week with a hamstring injury, while high marking small forward Jamie Elliott has resumed running on his return to fitness from a back injury.
