BERLIN (AFP) - Germany winger Marco Reus has refused to press charges of grievous bodily harm against a defender for a foul during a German Cup match, despite a two-month long police investigation.

Reus lasted just 24 minutes of Dortmund's 2-0 third-round win over third-division Dynamo Dresden and was left with a knee injury after being fouled off-the-ball by Dresden defender Dennis Erdmann.

Having investigated Erdmann for what was seen as a malicious, rather than sporting challenge, Dresden police have confirmed they have closed the matter.

"We've closed the case because the affected player has not made a complaint," a spokesman for the Dresden Prosecutor's Office said.

Reus' adviser Dirk Hebel told German daily Bild that the German international was sent a form by Dresden police asking if he wanted to press charges, but declined.

"He didn't want the player to be prosecuted," explained Hebel after his client was left with a bruised knee from the incident.
