It was a rough week for NFL linebackers in Week 1, most notably Baltimore's Terrell Suggs. The six-time Pro Bowl selection tore his left Achilles' tendon, an expected season-ending injury, in the Ravens' 19-13 loss at Denver on Sunday, coach John Harbaugh announced.

"I don't even know what happened out there," Harbaugh said. "All of a sudden, I look back and he was on the ground. But these are the things in life that happen. Adversity is all about how you respond to it, how you react to it."

Ravens linebacker Elvis Dumervil said it was a huge loss.

"You can never replace a Terrell Suggs, a big emotional leader for our team," Dumervil said. "It hurts everybody, whenever you hear news like that."

Suggs, a 32-year-old Minneapolis native, also tore his right Achilles in 2012, but that injury occured in the offseason, and he was able to play eight games that season.

• SURPRISE HONOR: The Buffalo Bills made late coach Lou Saban the 30th member of their Wall of Fame at halftime of Sunday's home opener. The team kept the honor a secret from Saban's four children, who were visibly emotional in celebrating their father's honor during a halftime ceremony. Saban coached the Bills from 1962 to '65 and again from 1972 to '76, leading the team to consecutive AFL championships in 1964-65. He died in 2009 at age 87.
