BATH director of rugby Todd Blackadder could find himself short of centre three-quarters for the trip to Saracens after Aled Brew suffered a suspected broken wrist early in the 17-15 win over Northampton.

The former Crusaders coach was already without Wales international Jamie Roberts, who is sidelined for up to six weeks with a fractured cheekbone, as well as long-term absentee Jonathan Joseph and Max Clark, due back soon after a hamstring injury.

Blackadder said of Brew's injury: "It's possibly (a broken wrist). He'll have to have an X-ray but it doesn't look good."

Asked if he would need to bring in cover for the centre positions, he added: "We'll look to make sure we have enough numbers but young Max Wright had a good first game when he came on."

Sam Underhill is another concern after being taken off having had treatment on the field. The flanker has had lay-offs for concussion in the past but Blackadder suggested the latest injury was a 'stinger' in the shoulder-neck area rather than a head injury.

Blackadder hailed his pack's scrummaging effort after a nail-biting victory, only secured when Dan Biggar hit the post with a conversion in the dying seconds.

"It was a really tough game - you want to be the team that wins in conditions like that out there," he said.

"I really felt at half-time that while we did not have a lot of territory, we were quite physically dominant. But a little lack of control and poor discipline let them back into it. We'll take a lot out of that game, though.

"We definitely had an edge in the scrums and in the second half our line-out went a lot better. Our line speed was good too... but there were little moments when we should have been more alive."

Chris Boyd, Northampton's new director of rugby, said: "Our line-out has been operating particularly well, but it didn't today.

"That didn't allow us to build enough pressure. We still had plenty of chances to win that game.

"We talked at half-time about having played just a little too much rugby but the boys said the ball was particularly slippery so we felt we might get a better return by finding space behind their players.

"But it wasn't until Dan Biggar put the cross-kick up for Harry Mallinder that we were in a position to contest the ball aerially.

"Their try just before half-time was a disappointment but none of the tries today were particularly clinically constructed."
