Sunderland have suspended Titus Bramble following his arrest for alleged sexual assault and possession of a Class A drug.
The 30-year-old was released on bail last night after being arrested in the early hours of yesterday morning.
"Sunderland AFC has confirmed that Titus Bramble has been suspended from duties, pending the outcome of a club investigation," a club spokesperson said.
"The player will not attend team training or be available for selection for matches during this period.
"The club is unable to make any further comment on the matter at present."
Sunderland next play on Saturday, when they host West Bromwich Albion in a Premier League clash.
