The 27-year-old England international, arrested two weeks ago, had his bail extended by five weeks on Tuesday and does not need to report back to police until April 23.
In response, Sunderland released a statement saying: "Following the police decision, the club will be reviewing its position."
The announcement came a day after the club appointed Dick Advocaat as manager following the dismissal of Gus Poyet.
Johnson, who has won 12 caps for England, has been suspended by Sunderland pending the outcome of the police investigation.
Johnson began his career with Middlesbrough and returned to his native northeast in 2012 when he joined Sunderland from Manchester City in a £10 million ($15 million, 13 million euros) deal.
