Giddens (knee) was a full participant in Wednesday's practice.
Giddens has yet to participate in a regular-season game this season. The running back missed the Colts' Week 1 loss to the Ravens as a healthy scratch before missing the Week 2 overtime loss to the Chiefs with a knee injury. The No. 3 back is now healthy and should be available for the Week 3 game against the Texans.
