The tackle, which occurred in the first term of Carlton's 30-point loss, was graded as Careless Conduct, High Impact, High Contact.
Hayes and the Blues have since accepted the two-match ban with an early plea, seeing him miss upcoming matches against the Giants and Crows, with a return potentially coming against Brisbane in Round 21.
The contact, against umpire Stephens, occurred in the fourth quarter and has been graded as a $1500 fine. Cameron can accept a $1000 fine with an early plea.
Young Pie Beau McCreery has also been hit with a financial sanction after being charged with Striking. The first term incident involving Crow Patrick Parnell was assessed as Intentional Conduct, Low Impact, Body Contact. The 21-year-old can accept a $2000 fine with an early plea.
Richmond's Toby Nankervis has had his match day report thrown out. The 27-year-old had been reported for rough conduct against North Melbourne's Flynn Perez, with the match review deeming that the incident did not "constitute a reportable offence".
The match review findings from Sunday's action will be released on Monday evening.
