Albion's FA Cup fourth round opponents West Brom are pursuing unsettled Newcastle midfielder Isaac Hayden.
Newcastle have reportedly rejected an approach from the Championship promotion contenders for Hayden, who was on the Seagulls' wanted list at one stage last summer.
Hayden has been seeking a move further south for family reasons.
Albion's interest in him diluted once they sealed the signing of Yves Bissouma from Lille.
Hayden will not be able to face the Seagulls at the Amex later this month if he ends up moving to the Hawthorns, as he started Newcastle's 1-1 home draw with Blackburn in the third round.
