Tim Membrey, Easton Wood and Levi Greenwood have all been offered bans, while Adelaide skipper Taylor Walker has escaped a suspension.
The Match Review Panel (MRP) released their statement on Monday afternoon after Round 16's action, with St Kilda forward Membrey copping a two-game ban for his strike on Richmond's Dylan Grimes.
The MRP said: "Based on the available video evidence and a medical report from the Richmond Football Club, the incident was assessed as careless conduct with high impact to the head. The incident was classified as a three-match sanction.
"The player has no applicable record which impacts the penalty. An early plea enables the player to accept a two-match sanction."
Western Bulldogs stand-in skipper Wood and Collingwood midfielder Greenwood can both accept one-game bans for strikes on Adelaide's Mitch McGovern and Essendon's Zach Merrett respectively.
Meanwhile, Walker was charged with misconduct after bumping Bulldogs defender Jason Johannisen into the post in Friday's match.
Walker can accept a $1000 fine with an early plea.
Luke Hodge, Trent Cotchin, Drew Petrie and Robbie Tarrant can also all accept financial sanctions for incidents.
The AFL has also said it will investigate an incident between Melbourne's Clayton Oliver and a Carlton fan at the MCG on Sunday.
