FC Barcelona Lassa's leading scorer Kevin Seraphin will miss at least another four weeks due to a right knee injury, the team announced Tuesday. Seraphin, 28, has been sidelined for three weeks already, but has not responded satisfactorily to the initial treatment. Barcelona's medical team, after consulting with international experts in the field of sports traumatology, will continue the current treatment for another month before reevaluating his progress. In his first season with the club, Seraphin leads Barcelona in scoring (12.1 ppg.), offensive rebounding (1.7 rpg.) and blocks (0.9 bpg.).
