The midfielder, who spent last season on loan in the Championship with QPR, could have put his future at Upton Park in doubt following another brush with the law.
Morrison, who spent last season on loan at QPR, will appear before magistrates Thursday following the alleged attacks on a 19-year-old and 39-year-old.
The talented 21-year-old was only recently handed a lifeline by Hammers boss Sam Allardyce, who indicated he was keen to keep the youngster at Upton Park for the coming campaign, but it now appears the former Manchester United youngster's future at the club has been thrown into question.

A statement from Greater Manchester Police said: “A man has been charged after two women were assaulted. Ravel Morrison, of Urmston, is charged with two common assaults. He is due before Manchester and Salford Magistrates' Court on 31 July 2014.
“At about 3.20am on Sunday 27 July 2014, police were called to an address on Alexandra Road, Peel Green, Salford, following reports a 19-year-old woman and a 39-year-old woman had been assaulted. Officers attended and established the young woman had also been assaulted outside a bar in Manchester city centre earlier that evening and a 21-year-old man was subsequently arrested at a later date."
Morrison has had a troubled past, receiving a police caution for assaulting his mother and twice being arrested on domestic abuse allegations in the past before charges were dropped.
He has also been the subject of a 12-month referral order following two court appearances in 2011, in which he admitted to intimidating a witness.
