West Bromwich Albion have signed winger Mikey Johnston on loan from Scottish Premiership giants Celtic.
The 24-year-old Glasgow-born Republic of Ireland international's deadline day move makes him boss Carlos Corberan's third January window loan deal.
He follows the signings of strikers Andi Weimann from Bristol City and Callum Marshall from West Ham United.
"I want to hit the ground running and make an impact right away," said Johnston.
"I think the deal has been rumbling on since the start of the window, so I'm just happy to get it over the line.
