Smythe was diagnosed with a torn Achilles tendon following an MRI on Monday and will require season-ending surgery, Ian Rapoport of NFL Network reports.
Analysis:The Ravens had been concerned that Smythe ruptured his Achilles during Sunday's win over the Titans, and the MRI ended up confirming the team's fears. The 31-year-old tight end suited up for each of the Ravens' first four games, serving mainly as a blocker while contributing a four-yard reception on two targets. He'll be ticketed for free agency in the spring after signing a one-year, $3 million deal with Baltimore in the offseason.
