Rockies RP Rafael Betancourt to start rehab assignment Sunday

Rockies right-hander Rafael Betancourt is expected to make a Triple-A rehab outing with Albuquerque on Sunday, according to MLB.com.

Betancourt has been on the disabled list since June 8 due to symptoms of vertigo and a sinus infection. It is not clear how many rehab outings Betancourt will need before being able to return to the Rockies' bullpen.
