On Saturday, Bournemouth play Fulham in the Premier League.
But they will be without 21-year-old Alex Jimenez.
The reason for his suspension is that Jimenez is suspected of posting inappropriate messages on social media.
"Bournemouth are aware of posts circulating on social media involving right-back Alex Jimenez," the club wrote on its website.
"The club understands the seriousness of the situation and the matter is currently being investigated."
