Rupp was/is scheduled to race a 5k in Dusseldorf Germany this weekend vs Paul Koech (4th fastest ever indoors).
However, today in an article on Mo Farah trying to break the British 5k indoor record in Birmingham in 2 weeks, they said he's racing Galen Rupp. Start lists here:
Rupp is still on the starts lists in Germany:

Rupp dropped out of a mile race earlier this year with asthma.

My guess is Rupp will skip Dusseldorf and run in Birmingham, but no confirmation of this.
