Graham (knee) will need surgery to repair his patellar tendon, NFL.com's Ian Rapoport reports.
Seahawks head coach Pete Carroll said Graham will be out for the rest of the season. The tight end presumably tore his patellar tendon, which means he's no lock to be ready for training camp next year. Luke Willson will take over as the Seahawks' top tight end, with Cooper Helfet serving as the No. 2. The Seattle wide receivers may also see a few more targets due to Graham's absence.
