The Rams signed Mundt to a one-year deal on Thursday, Jourdan Rodrigue of The Athletic reports.
Mundt, who's spent the past four seasons in Los Angeles primarily serving as a blocking tight end, caught all four of his targets for 53 yards in 2020. It will likely take a few injuries for the 26-year-old to play a larger role in the team's passing plans, but Mundt will aim to continue seeing more playing time in 2021.
