The Green Bay Packers have added three players at tight end over the past few days, a quiet but telling flurry of moves driven by injuries and depth questions at the position. The Packers signed Thomas Yassmin, McClellan Castles, and Drew Biber. Training camp has exposed a thin roster behind the top options, and general manager Brian Gutekunst’s front office is scrambling to find cheap alternatives before the regular season.

Injuries forcing Green Bay’s hand

The Packers already entered camp with depth concerns at tight end. Those concerns escalated when Luke Musgrave suffered a neck injury that has kept him out of practice in the short term. The team also lost recently signed Luke Lachey, who was spotted in a walking boot this week at practice, and undrafted rookie RJ Maryland. Both have now been waived/injured.

Tucker Kraft and, to a lesser extent, Musgrave remain the primary answers at the position. But with both Musgrave, Lachey, and Maryland sidelined, Green Bay needed bodies to get through training camp and evaluate whether any of them could provide meaningful depth ahead of the regular season.

3 additions in quick succession

The first signing was international player Thomas Yassmin, an Australian tight end who is part of the NFL’s International Pathway Program. Yassmin went undrafted in 2024 but has some NFL experience, having spent time on the practice squads of the Denver Broncos and the Los Angeles Chargers. He also logged training camp reps with both teams. Yassmin is mostly a bottom-of-the-depth-chart piece who doesn’t count toward the 90-man roster, which motivated the Packers to bring in two more players at the position.

The second addition was McClellan Castles, a 26-year-old who spent time on Green Bay’s practice squad in 2025. Castles played collegiately at UC Davis and Tennessee, and he has bounced around the NFL with stops in Philadelphia, Los Angeles (both the Chargers and Rams), and Green Bay. The Packers signed him last November after Kraft got hurt, but he landed on the practice squad injured reserve list in January. He was released in April before the draft and now returns to Green Bay for another opportunity.

The third signing was undrafted rookie Drew Biber, a former Purdue tight end who transferred to Minnesota for his senior season. Biber’s college production was modest: 33 receptions for 271 yards and one touchdown across five seasons. He was the 37th tight end in the draft class, according to Dane Brugler of The Athletic.

None of these three players project as contributors on the 53-man roster. The Packers are looking for cheap, low-risk options to fill out the depth chart during training camp and provide enough bodies to run the offense in practice. The real tight end picture in Green Bay still centers on Kraft as the starter, with Musgrave (when healthy) and Josh Whyle as the complementary pieces.
