Werder Bremen's Baumann hit by battery

The German Football Association (DFB) has opened an investigation after Werder Bremen captain Frank Baumann was hit by a mobile phone battery thrown from the crowd during Sunday's 2-1 defeat away to Hamburg SV.

Baumann was hit on the head while Werder were celebrating their first half equaliser and the DFB said in a statement it was looking into the incident.

"It was a bit of a shock," Baumann told reporters. "It hurt a bit, and it bled a bit, but I was able to carry on."
