Bath will have to do without England internationals Sam Underhill and Ollie Lawrence against Castres at Stade Pierre-Fabre tonight.

Flanker Underhill and centre Lawrence sustained "knocks" during Bath's 33-26 Prem win over Exeter on Saturday, with no detail on how long they could be out of action.

Miles Reid joins Ted Hill and last week's man of the match Alfie Barbeary in the back row, with Guy Pepper stepping down to the bench to take Underhill's place.

England international Max Ojomoh starts alongside Cameron Redpath in the centres having recovered from a calf injury.

Quinn Roux comes back into the starting line-up at the expense of Italian international Enoch Opoku-Gyamfi, who made his Prem debut against Exeter.

Every side in Pool Two has won one match after two rounds but Bath, who won the Challenge Cup last year after making an early Champions Cup exit, are the only one to have two bonus points and lead the way with six points.

Johann van Graan's side lost 45-34 to Toulon in their previous Champions Cup game in December, but enjoyed a big home win over Munster in their opener.

Castres, who are second, thrashed a much-changed Edinburgh side 33-0 last time out but lost 34-14 against Gloucester in their first match.

In a tight pool it's very much all to play for tonight.

Good evening and welcome along to the beginning of a weekend packed with Champions Cup action from all over Europe and South Africa.

Since the first two rounds were played in December we've all enjoyed the Christmas break and welcomed in 2026.

The new year may only be in its infancy but it's already crunch time with the fixtures this weekend and next determining who will earn themselves an all-important home draw in the knockout stage, who faces a tricky away trip and who will be eliminated from Europe completely.

Stick with us to find out who will still be in the mix when spring comes along as the best sides around set their sights on making it all the way to the final in Bilbao.
