Baltimore Ravens cornerback Marlon Humphrey was diagnosed with a season-ending right pectoral muscle tear on Monday.

Humphrey, 25, became the seventh starter (and third in the secondary) to get sidelined for the season for the Ravens.

He was injured in Sunday's 20-19 loss in Pittsburgh to the Steelers when he tried to tackle Diontae Johnson before the wide receiver scored the go-ahead touchdown late in the fourth quarter.
