Redskins linebacker Junior Galette has torn Achilles’ tendon

Washington Redskins Coach Jay Gruden said outside linebacker Junior Galette will miss the entire season after tearing his left Achilles’ tendon.

Gruden discussed Galette’s status on Thursday, a day after the pass rusher was injured toward the end of practice. Gruden said Galette is scheduled to have surgery Friday.

Galette had missed Washington’s first two exhibition games as he worked his way back from an injury to a chest muscle.

He is the fifth Redskins player lost to a season-ending injury in the preseason, including tight ends Niles Paul and Logan Paulsen.

Packers’ Guion suspended

The 28-year-old Guion was arrested near his home in Florida in early February on felony charges of drug and firearm possession. A traffic stop turned up three-quarters of a pound of marijuana, a handgun and a bag containing more than $190,000 in cash.
