Graham (knee/back) was a non-participant at Thursday's practice, John Boyle of the Seahawks' official site reports.
Just as Graham appeared to establish himself as a viable option for Russell Wilson (ankle/knee), the tight end was unable to practice Thursday due to an undisclosed back injury. Graham is expected to be a key target for the hobbling Wilson, whose lack of mobility have the potential to guarantee sustained looks for the foreseeable future. The Seahawks will wait out Friday's practice to learn of Graham's potential to play in Week 4, but a fog currently hangs over his status.
