The mood at the Cleveland Browns’ offseason practice complex shifted dramatically on Tuesday afternoon when cornerback Martin Emerson Jr. planted his left foot at the end of a 7-on-7 drill, collapsed to the turf and was unable to bear weight as teammates and trainers rushed to his side.

A key development: The Browns went live tackling in the final team period — a major shift from previous camps. This was the first full-speed live tackling session in at least four years. It’s a critical step in acclimating players to real-game contact tempo and builds the physical resilience needed early in the season.

With Quinshon Judkins currently away from the team, there's uncertainty at RB. And outside of Jerry Jeudy, the WR position is wide open.
