Dolphins’ post-draft updates: The undrafted rookies who committed to Miami Saturday night

The Dolphins on Saturday evening began the process of signing undrafted rookies free agents by agreeing to terms with a player who never played in a college football game -- offensive lineman Bayron Matos, a former college basketball player at the University of New Mexico.

Matos, who was born in the Dominican Republic, has some football experience. Matos joined USF as a walk-on in 2022. He was initially a defensive lineman but then moved to the offensive line and didn’t appear in a game.

This past January, Matos was announced as one of 16 players selected for the NFL’s International Player Pathway Program, designed to give opportunities to foreign players.

He trained at IMG Academy in Bradenton, and former Chiefs GM Scott Pioli has praised his skills. He was considered a potential late-round pick.

At 6-9 and 290 pounds, he runs well for his size -- a 4.88 in the 40-yard dash.’s Lance Zierlein said “Matos is a decent athlete, but he’s not as sudden or fluid in his lateral movements as I expected. His pro-day workout featured good protection posture and inside hands with a crisp punch, but he’ll need extensive practice time and coaching to get to where he needs to be as a pro. He’s likely to be stashed on a practice squad early on in his career.”

The Dolphins then added UTEP center Andrew Meyer, who received $75,000 guaranteed, according to a league source.

Others who agreed to terms with Miami:

7:45 p.m. update: The Dolphins signed TCU safety Mark Perry, who had three interceptions for Colorado in 2021, and 142 tackles and 6 passes defended at TCU over the past two years. Perry ran an impressive 4.37 in the 40 yard dash.

Perry, 6-0, played three seasons at Colorado and the past two at TCU. He had 15.5 tackles for loss, two sacks, those three interceptions (all coming in 2021 with the Buffaloes) and 10 passes defended over five college seasons.

The Dolphins gave him $165,000 guaranteed, according to a source.

7:58 p.m. update: UCLA edge player Grayson Murphy agreed to a deal with the Dolphins. Murphy chose the Dolphins over multiple offers. He didn’t work out for Miami.

He began his career at North Texas and had three sacks and four tackles for loss in 2020 and 8.5 sacks and 14.5 tackles for loss in 2021.

Then he transferred to UCLA, where he produced nine tackles for loss and five sacks each of the past two seasons. He’s 6-2 and 235 pounds.

8 p.m. update: The Dolphins agreed to a deal with FAU receiver Je’Quan Burton, who caught 24 passes for 277 yards (11.5 per catch) and two touchdowns last season.

He had 84 catches for 1277 yards and nine TDs in three seasons for FAU.

8:05 p.m. update: UTEP quarterback Gavin Hardison is signing with the Dolphins. He threw for 7963 yards and completed 53.7 percent of his passes with 40 TDs and 33 picks over five seasons.

He played less last season than the previous three because his season ended with Tommy John surgery on his throwing elbow in November; he had five TDs and seven interceptions before his injury.

Skylar Thompson remains the front-runner for the No. 3 quarterback job.

8:08 p.m. update: The Dolphins are signing Louisville cornerback Storm Duck, who had five interceptions in four years at North Carolina before transferring to Louisville, where he had 32 tackles and seven passes defended and a sack in 13 games last season, his only one playing for the Cardinals.

How much did the Dolphins want Duck? They gave him a $20,000 signing bonus and $150,000 guaranteed, per a source. Multiple Dolphins staff members called him and he picked Miami over a dozen other offers.

8:10 p.m. update: Syracuse cornerback Isaiah Johnson committed to join the Dolphins. He had 59 tackles, a forced fumble and an interception in 2023. He started every game last season and PFF rated him Syracuse’s second best defensive player.

Johnson had 188 tackles, 2.5 sacks, 14 pass breakups and three interceptions in his college career, which started at Dartmouth.

8:20 p.m. update: This is significant: The Dolphins agreed to a deal with Ohio State guard/center Matthew Jones, who started 24 of the Buckeyes’ 26 games the past two seasons and was second team All Big 10 last season.

“Jones has talent as a move blocker and pass protector,”’s Lance Zierlein said.

8:45 p.m. update: And then there’s the story of Texas Tech cornerback Rayshad Williams, who was widely reported to be joining the Dolphins but is instead joining the Raiders.

Here’s what happened, per his agent Ron Hawthorne: A veteran Dolphins front office official left for the Raiders. Williams camp thought they were talking to Dolphins on the phone tonight, but the front office official -- whose name was not revealed -- now works for the Raiders and that wasn’t clear to Hawthorne.

The Williams camp called the Dolphins for clarity and the Dolphins offered a camp invite. Raiders offered a full contract, and thus he opted for Las Vegas instead.

9:05 p.m. update: Colorado defense tackle Leonard Payne is joining the Dolphins. The 315-pounder played four years at Fresno State and one year at Colorado.

He started seven games and played in 12 for Colorado last season and had 10 tackles (two for loss) and three sacks, a forced fumble and a blocked kick.

In 28 games over four years at Fresno State, he had 35 tackles, including 10.5 for loss and 5.5 sacks.


Four undrafted Miami Hurricanes committed to teams after the draft: guard Javion Cohen with Cleveland, defensive tackle Leonard Taylor with the Jets, defensive tackle Branson Deen with Buffalo, receiver Tyler Harrell with the Jets (per his agent, former Canes standout Melvin Bratton) and linebacker KJ Cloyd with Minnesota.
