Ghanaian pair Gideon Jung and Jan Gyamerah missed SV Hamburg pre-season training due to injuries.
Hamburg commenced their pre-season training last two weeks ago ahead of the new season which kicks off next month but without Gideon Jung and Jan Gyamerah who are facing spells on the sidelines.
The Ghanaian pair are suffering from muscular problems but are expected to recover in time for the start of the Bundesliga 2 campaign.
Jung missed large part of last season through injury, making only 14 appearances in all competitions and registering one assist.
On the other hand, Gyamerah spent the last term on loan at VfL Bochum and managed to feature 25 games.
The duo are expected to play key roles for Dieter Hecking's outfit in the upcoming Bundesliga 2 campaign.
Hamburg finished 4th last term and will be eager to secure promotion into the top flight.
