Peter Mata'utia is set to miss Castleford Tigers' next two fixtures after being hit with a two-match penalty notice.
The utility back, who was deployed at centre in yesterday's opening-day win over Toronto Wolfpack, has been charged with a Grade B Dangerous Contact for a late hit on Wolfpack forward Jon Wilkin.
It means the 29-year-old will miss this Friday's meeting with Wigan Warriors and the following fixture with Catalans Dragons.
Castleford got their Super League campaign off to a winning start with Mata'utia crossing for the Tigers' final try at Headingley in a 28-10 win.
Liam Kay opened the scoring for the Wolfpack but Greg Eden, Grant Millington, Adam Milner and Michael Shenton - in his first competitive appearance since last April - hit back for Castleford.
Hakim Miloudi replied for Toronto in the second period as he sprinted clear after intercepting a pass from Jordan Rankin.
Warrington Wolves forward Chris Hill has also been issued with a penalty notice for a Grade C High Tackle in the Wire's loss at Wigan Warriors.
The veteran prop was sent off in the first half for a high tackle on Sam Powell and is set to be suspended for the next three games.
