The defender completed his move from Houston Dynamo after finalising his work permit.
Boss Derek Adams will be without midfielder Stuart Kettlewell (hamstring).
New Hibernian signing Scott Robertson will go straight into Pat Fenlon's squad.
The twice-capped Scotland international and former Dundee United midfielder has moved to the Easter Road outfit on a two-and-a-half year deal and could make his debut in the Clydesdale Bank Premier League fixture at the Global Energy Stadium in Dingwall.
Fenlon, however, is still sweating on the fitness of on-loan Manchester City defender Ryan McGivern, who could miss out with a hamstring injury.
