Albion are hoping for good news on Adam Lallana after his Liverpool reunion was cruelly cut short.

The midfielder made a brief appearance off the bench before suffering a reaction to the groin niggle which had troubled him all week.

Graham Potter was confident neither Lallana nor Neal Maupay (hamstring) were facing significant lay-offs.

But he will know more today.

Lallana was able to run off the pitch and down the tunnel as he made way.

Potter said: “It was just one action that opened it up and probably felt it.

“Again, it’s a learning point. You try these things. I knew he wasn’t ready to start because of the intensity of the game.

“I thought I might be able to get him at the back end but it wasn’t to be. We’re hoping that it’s not too bad.”

Injuries meant Potter only had one tactical change available to him and he saw Danny Welbeck require treatment when all three subs were in.

The Albion boss remains supportive of allowing five substitutions per team per match in the Prem.

He said: “I was for it and we voted for it. I’m for it again because I think it’s good on lots of levels.

“But it’s not to be at the moment and we have to get on with it.”
