On Monday, Dolphins general manager Jon-Eric Sullivan continued to churn the bottom of the team's roster - signing tight end Ethan Conner and inside linebacker Jaheim Thomas while waiving center Jim Bonifas and cornerback Ahmari Harvey.

The moves come after Dolphins rookie linebacker Trey Moore suffered a non-disclosed injury during Saturday's preseason contest against the New York Giants that will keep the defender on the shelf for some time.

Miami's website had this to say about Thomas:

Thomasappeared in 10 games with the Louisville Kings of the United Football League during the 2026 UFL season, recording 64 tackles (42 solo), 0.5 sack, 1.0 tackle for loss and two passes defensed. He also appeared in two postseason games and helped the Kings capture the 2026 United Bowl title. Thomas finished his collegiate career at Wisconsin (2024) after spending time at Arkansas (2023) and Cincinnati (2020-22). He appeared in 52 career games with 21 starts and recorded 236 tackles (97 solo), 7.0 sacks, 15.5 tackles for loss and two passes defensed during his collegiate career."

They also had this to say about their new tight end:

Conner entered the NFL as an undrafted college free agent with Jacksonville on April 27, 2026, and spent the offseason program and part of training camp with the Jaguars. He played three seasons at Troy (2023-25), where he appeared in 28 games with 17 starts and recorded 59 receptions for 680 yards (11.5 avg.) with seven touchdowns. He transferred to Troy from East Mississippi Community College following the 2022 season."

Time will tell if either player will have enough time to make an impact before the league's official cut-down day taking place this upcoming Sunday.
