Recent Eintracht Frankfurt signing Ricardo Clark has been sideline for up to four weeks after pulling a calf muscle in training.

The 26-year old ex-Houston Dynamo midfielder will now have to wait to make his German Bundesliga debut with his new club after manager Michael Skibbe said he needed a few weeks of training to get back in condition.

Clark signed with Eintracht in January as a free agent after his contract with the Dynamo ended at the end of the 2009 MLS season.
