Packers add tight ends McCallan Castles and Drew Biber, make additional roster adjustments

The Green Bay Packers announced a set of tight end roster moves on August 4, adding depth while also making changes that affect their current group at the position. General Manager Brian Gutekunst’s announcement, made by the team, included the signing of tight ends McCallan Castles and Drew Biber.

As part of the same transaction list, the Packers also addressed the status of two other tight ends. Luke Lachey and RJ Maryland were waived/injured, according to the team’s release. The sequence is typical of NFL roster management in August, when clubs balance veteran experience, developmental prospects, and the realities of practice-squad and injury considerations.

Castles’ and Biber’s signings give the Packers two additional players in a room that is often asked to do more than one job. Tight ends in the NFL are expected to contribute in the passing game as receiving targets and, depending on personnel groups, to provide blocking support in the run game. Adding bodies in August can increase practice repetition for route work, run-blocking schemes, and special teams opportunities.

For the players themselves, the transactions offer a clear look at what the Packers prioritize during roster construction. The team did not describe specific role assignments in the announcement, but the timing suggests an emphasis on evaluating performance during offseason and preseason work, especially for players competing for limited spots behind the established starters.

The waived/injured designations applied to Lachey and Maryland indicate that the Packers are not simply reshuffling depth but also accounting for the players’ health status as the team moves through the early stages of the roster-building window. In practice, a waived/injured process can create outcomes such as a player returning to the organization if they clear waivers under injury-related terms, though the precise result depends on waiver and subsequent league processes.

With multiple tight ends affected, the Packers’ next period of evaluation will likely center on who can be trusted for consistent reps at practice speed and in game-like situations. Tight end depth also has knock-on effects for offensive personnel groupings, since substitutions among tight ends can influence the distribution of snaps across wide receivers, running backs, and blockers.

The immediate takeaway is that Green Bay is continuing to adjust its roster composition at a position where the margin for error is often thin. As the offseason progresses into preseason and final roster decisions near the regular-season threshold, the competition among tight ends will become more distinct, and the impact of the signings and waived/injured moves will be reflected in who earns the most practice reps and, ultimately, roster spots.
