FOXBORO, Mass. — New England Patriots linebacker Jamie Collins was not present at Thursday’s training camp practice — the first one of the summer.

The reason for his absence is unknown, but Patriots head coach Bill Belichick confirmed before Friday’s session that Collins was “excused” from Thursday’s practice and that there are “no issues.”

Collins was present for Friday morning’s practice at Gillette Stadium.
