Nike have suspended their relationship with Manchester United's Mason Greenwood following an investigation by Greater Manchester Police into allegations of rape and abuse of a woman.
Greenwood was arrested on Sunday after the allegations were posted on the Instagram account of a woman who uploaded images of bruising to her body and bleeding from her lip.
A voice note purporting to be of an attack was also posted. The posts were all deleted from the social media site but were widely shared.
Nike said in a statement on Monday, "We have suspended our relationship with Mason Greenwood. We are deeply concerned by the disturbing allegations and will continue to closely monitor the situation."
GMP said the 20-year-old remains in police custody on Monday after investigating officers were granted more time to question him.
A police statement read, "Detectives have been granted additional time to speak to a man in his 20s who is being held on suspicion of rape and assault of a woman.
"The suspect was arrested yesterday afternoon and remains in custody.
"Enquiries are ongoing and the victim is being offered specialist support.
We remind people to avoid any commentary or sharing of images that could compromise the victim's right to lifelong anonymity, or risk prejudicing a live investigation with active proceedings."
United said Greenwood "will not return to training or play matches until further notice."
Greenwood, who has scored six goals this season, has a United contract through 2025.
