Cliftonville defender Michael Newberry has died suddenly at the age of 27.
The English defender joined the club in the summer and made 25 appearances for the Reds.
Newberry, who started his career with hometown club Newcastle United, also had a spell in Iceland with Vikingur before he joined Linfield in 2021.
The former Northern Ireland Under-21 international spent three years with the Blues, winning two Irish Premiership titles and the Irish Cup.
Cliftonville’s game against Dungannon Swifts and Linfield’s match with Larne on Monday night have both been postponed.
In a statement posted on the club’s website, Cliftonville said they were “devastated”.
“Our condolences are extended to Michael’s family and friends, as well as the many team-mates he played with during his career, and fans who will be shaken and saddened by this heartbreaking news,” their statement added.
“Rest in peace, Newbs.”
