Hull FC prop Liam Watts is facing a three-match ban for the headbutt which earned him a fourth red card in under 12 months.
Watts was sent off following the clash with Warrington front rower Dom Crosby during Hull's 21-12 Betfred Super League win on Friday night.
The Rugby Football League's match review panel deemed it a grade C offence and Watts has until 11am on Tuesday to accept the three-match penalty notice or face a disciplinary hearing.
Watts was sent off three times in 2017 and his previous record means he received a penalty notice at the higher end of the range.
Warrington half-back Declan Patton, who was also sent off in the game at the KCOM Stadium, is facing an even bigger ban after being referred to the RFL's operational rules tribunal for a grade D high tackle on Hull winger Bureta Faraimo.
Patton's team-mate Sitaleki Akauola, who is just two matches into his Super League career, is also in danger of missing Friday's derby with St Helens after being handed a one-match penalty notice for a grade B dangerous tackle in the same game.
Hull centre Carlos Tuimavave will face no further action after receiving a grade A penalty notice for a dangerous tackle in that feisty match.
Second rowers Daniel Smith (Huddersfield) and Matty Ashurst (Wakefield) were both handed one-match penalty notices for dangerous tackles during Trinity's 22-4 win over the Giants on Sunday.
Former Wigan forward Eddy Pettybourne has been given a three-match ban for a high tackle during Toulouse's Betfred Championship win over Leigh.
