Hoops defenders fight for Old Firm derby fitness

Celtic defenders Joos Valgaeren and Ulrik Laursen are facing a race against time to be fit for the crucial Old Firm derby at Ibrox on Sunday.

Former Hibernian man Laursen has not featured since the 3-2 win at Dundee United on March 19 and his replacement, Valgaeren, picked up an ankle knock in the win over Aberdeen at Celtic Park on Saturday.
