SAINTS loose forward Morgan Knowles has been handed a Grade B dangerous contact charge and a one-match penalty notice.
He will miss Thursday night's trip to Huddersfield Giants - unless Saints appeal and win that appeal.
The charge stems from a late hit on the passer.
There was no further action for Hull prop Ligi Sao's high shot on Tee Ritson, with the panel deeming it hit the shoulder and rode up.
However, Hull wing Davey Litten has been fined £250 for his use of the legs in trying to stop Jon Bennison from scoring.
Saints were not awarded an 8-point try on the night for that challenge.
Following the latest round of Betfred Super League fixtures, the Match Review Panel have issued the following sanctions.
Morgan Knowles, St Helens Dangerous Contact B 1 Match Penalty Notice.
James Bentley, Leeds Rhinos Dangerous Contact B 1 Match Penalty Notice.
Joe Westerman, Castleford Tigers Dangerous Contact B £250 fine.
George Williams, Warrington Wolves Tripping B £250 fine.
Shane Wright, Salford Red Devils Dangerous Contact B £250 fine.
Davey Litten, Hull FC Other Contrary Behaviour B £250 fine.
Arthur Romano, Catalans Dragons Striking A No further action .
