Clemson forward Ian Fuller, drafted in the SuperDraft second round by New England last February, has signed an MLS contract. He has been rehabilitating an injury and played for the Revs in an exhibition match against Charleston earlier this month. Fuller takes the roster spot vacated by the departure of midfielder Shaun Tsakiris, who was waived last week. His presence puts more pressure on Wolde Harris and Andy Williams, who have dropped down the depth chart with Taylor Twellman's emergence as a partner for Mamadou Diallo.
