The club offered more detail on Hoffman in a statement: "Philipp Hofmann suffered a serious injury during VfL Bochum 1848's away game in Heidenheim. The VfL striker suffered a broken rib after a collision with his opponent Marvin Pieringer, with the rib piercing the pleura and causing a collapsed lung - a potentially life-threatening injury. Hofmann owes it only to the careful first aid and immediate examinations and actions at the local hospital that nothing more serious happened. A minor operation using chest drainage relieved the injury, restoring lung function. 'Hoffi' will remain in the hospital for observation and treatment until he is fit to be transported. VfL Managing Director Dirk Dufner visited him in the hospital this morning and conveyed the team's best wishes for a speedy recovery, which has since begun its journey home. For Philipp Hofmann, the injury means he will no longer be able to support the team on the pitch this season. We wish our number 33 all the best - 'Hoffi', you are a fighter, you can do it!"
