I'd be surprised if it wasn't Farrimond that French replaces. He's bounced back well from that tough game against Wire but they've still not really given him that responsibility of controlling the side and it was Keighran who seemed to do the bulk of that in this past couple of games. I doubt they'll change that this week and Keighran will do one more game in the halves until Smith is back.
I mean this in a good way but I hope that is the last we see of Farrimond until 2025. That will mean Field, French and Smith have all stayed fit and available and Farrimond can rest up and walk away happy with how the year has gone, ready to come back next year with plenty of confidence.
