Panthers injury game status: Out: WR Curtis Samuel (illness). Questionable: OT Daryl Williams (knee), OT-OG Amini Silatolu (knee), TE Chris Manhertz (foot). Ron Rivera says he’s “building confidence” that Williams and Silatolu can play Sunday. “They came in today pretty good,’’ Rivera said. “The last couple of days we’ve been able to increase their workload. Each day we get a little bit more, so we’ll see.’’
