Rotherham and Southend have been in dispute over Campbell-Ryce

The 22-year-old moved to Southend on a three-month loan in September.

However, Rotherham have claimed that there was an agreement between the clubs to make the move permanent for �100,000, but no money changed hands.

The Shrimpers have now agreed that the tribunal, which began in February, has jurisdiction to decide the matter.

"This is a breakthrough for us," Rotherham chairman Peter Ruchniewicz told his club's website.

"The way is now clear for a full hearing into the transfer."
