He led the NFL in punt return average last season, returning one 82 yards for a touchdown against the Houston Texans. Doss caught a career-high 19 passes last season for 305 yards.
Doss is a former Ravens fourth-round pick from Indiana.
"I'm incredibly excited about the opportunity to come to Jacksonville and compete for a spot right away,” Doss said. “I would like to thank Mr. Khan, Mr. Caldwell and Coach Bradley for this chance and I can't wait to get back here and get to work. I just want to get on the field in any capacity. If it's at wideout, or on special teams, I'm willing to play wherever they think I can help the team."
