Jim Mora announced during his press conference that fullback Justin Griffith sprained his MCL. That's the medial ligament of the knee. Without knowing the severity of the sprain, we cannot be sure of the treatment or timetable for Griffith's return. The MCL is less critical to the stabilization of the knee than the ACL. Isolated MCL strains are rare. The Seahawks will most likely allow the swelling to decrease and move from there. I do not think Griffith will need surgery. If Owen Schmitt is not able to capture starting fullback duties, Griffith should be able to return this season. Hopefully Schmitt learns on the job and seizes his potential.
