Gillotte suffered a strained hamstring during the Chiefs' training camp practice Friday, Matt McMullen of the Chiefs' official site reports.
Whether the injury will impact Gillotte's availability for Week 1 of the regular season will depend on the severity of the strain. As long as he's sidelined, Felix Anudike-Uzomah and rookie second-rounder R Mason Thomas will be candidates to see an uptick in reps on the edge.
