The Bills will be without defensive end Shaq Lawson and defensive back Taron Johnson on Sunday when they play the Los Angeles Chargers in the home opener at New Era Field.
Lawson started last Sunday in the 47-3 loss to Baltimore but was hampered by a pulled hamstring that continued to nag him this week in practice. The third-year veteran out of Clemson had a solid training camp and was being counted upon to help the pass rush, especially with free agent Trent Murphy slowed by a groin problem.
Johnson was assigned the slot receiver in passing situations and had two tackles against the Ravens. The 22-year-old rookie from Weber State did not practice this week after suffering a shoulder injury. The Bills are expected to start veteran Vontae Davis at cornerback and move Phillip Gaines into Johnson's spot covering the slot.
Rookie speedster Ray-Ray McCloud, who missed the opener with a sprained knee, was limited in practice and was listed as questionable for the game Sunday.
