Bournemouth head coach Gary O'Neil believes Marcos Senesi's injury is not severe.
The defender had to come off during a loss to the Albion, having played the first 85 minutes of the game.
Brighton were already up through an Evan Ferguson goal, but then made it two through Julio Enciso after Senesi's withdrawal.
Post-game, O'Neil told the Daily Echo: He felt something in his hamstring, so he doesn't think it's too serious, but yeah, he said he felt something when he was running back."
Senesi has been an integral figure for the newly promoted club this season.
The summer signing from Feyenoord has started 24 games in the Premier League.
