Saints No.8 Gerrit-Jan van Velze has been cited for an alleged tip tackle during the 24-21 win against Exeter Chiefs at Franklin’s Gardens on Sunday.
Van Velze was sin-binned in the 38th minute of the game after the TMO was brought into action and told referee JP Doyle to issue a yellow card for the challenge on Chiefs No.9 Will Chudley.
It was van Velze’s second sin-binning in as many starts for Saints since joining from Blue Bulls in the summer, after he was shown a yellow in the Premiership opening-day win at Gloucester.
The South African will find out the RFU’s verdict on the Exeter incident at a hearing on Tuesday.
Meanwhile, Bath centre Matt Banahan looks to set to miss the clash with Saints on Friday night after picking up a knee injury in the 30-23 win against Wasps at the weekend.
The England ace left The Rec in a brace after limping off during the closing stages of Saturday’s Premiership battle.
And he now looks unlikely to figure against Saints this week as two sides with 100 per cent records go head to head.
“Matt has damaged his knee and we will know more about it in the next 48 hours,” said Bath skills coach Brad Davis. “He will go to have a scan and we will wait and see what the results are, but he has been put in a brace.”
And head coach Toby Booth added: “All injuries are a worry. The people who are near the top of the table at the end of the season are the sides whose players stay fit and healthy, giving them more firepower at their disposal.
“We have a few dents in the squad already but we will have Sam Vesty, Stephen Donald and Tom Heathcote to come back soon.”
