West Brom have signed former Sheffield United defender Kean Bryan on a two-year deal, after confirmation that Dara O'Shea will be out for four to six months with a fractured ankle.
Bryan, 24, who left the Blades at the end of last season after turning down a new contract, was a free agent.
"I have been very impressed with Dara since I arrived here, and I know he will dedicate himself to the rehabilitation required to get back to full fitness.
"Fortunately, the club reacted very quickly to the injury and we have signed Kean Bryan to strengthen our defensive options during Dara's injury and beyond.
