Dallas Cowboys Sign Veteran Offensive Lineman Matt Hennessy to Bolster Depth During NFL Free Agency

The Dallas Cowboys made a subtle but strategic move along their offensive line Thursday night, agreeing to terms with veteran lineman Matt Hennessy as the team continues reshaping its roster during the early stages of NFL free agency.

According to Todd Archer of ESPN, the Cowboys finalized an agreement with Hennessy shortly after parting ways with interior lineman Brock Hoffman earlier in the week. While the financial details of Hennessy’s new contract were not disclosed, the veteran previously played under a two-year, $2.4 million deal with the San Francisco 49ers.

Though the signing may not generate headlines like blockbuster acquisitions, it reflects Dallas’ ongoing effort to strengthen depth along the offensive front as the team prepares for the upcoming season.

Who Is New Cowboys Lineman Matt Hennessy?

Matt Hennessy enters Dallas with several years of NFL experience and a reputation as a reliable interior lineman capable of filling multiple roles.

The 28-year-old, 6-foot-3, 315-pound lineman was originally selected in the third round of the 2020 NFL Draft by the Atlanta Falcons after a standout college career at Temple University.

Since entering the league, Hennessy has built a solid résumé that includes:

• More than 60 NFL game appearances

• 24 career starts

• Experience at both center and guard

Last season with the San Francisco 49ers, Hennessy appeared in every regular-season game and both playoff contests, though he started only twice.

Despite limited starts, his durability and versatility made him a valuable depth piece on one of the NFL’s most competitive rosters.

Timing of the Signing Raises Questions About Brock Hoffman

The Cowboys’ decision to add Hennessy came just two days after the team declined to tender restricted free agent Brock Hoffman, leaving his future with Dallas uncertain.

Hoffman had become a fan favorite during his time with the Cowboys thanks to his aggressive playing style and relentless attitude on the field.

Earlier reports suggested Hoffman had reunited with former Cowboys head coach Mike McCarthy by signing with the Pittsburgh Steelers. However, Hoffman quickly disputed that report, stating that he remains a free agent as of Friday.

While his status remains unresolved, Dallas’ signing of Hennessy strongly suggests the team is preparing to move forward with a different depth configuration along the offensive line.

Hennessy’s Versatility Adds Value to Dallas

One of the primary reasons the Cowboys targeted Hennessy is his positional flexibility. Like Hoffman, he has experience playing both center and guard, making him a useful insurance option in case of injuries.

Teams often rely heavily on versatile offensive linemen during long NFL seasons, especially when injuries inevitably test roster depth.

By adding Hennessy, the Cowboys gain a player who can:

• Step in at center if needed

• Provide depth at guard

• Offer reliable protection in rotational situations

• Contribute experience from multiple offensive systems

This type of versatility allows coaching staffs to make adjustments without dramatically altering offensive schemes.

A Highly Regarded Prospect Coming Out of College

Before entering the NFL, Hennessy was widely viewed as one of the top interior offensive line prospects in the 2020 draft class.

Interestingly, he was selected one round earlier than Tyler Biadasz, the center the Cowboys drafted that same year.

As reported by Todd Brock of USA Today’s CowboysWire, Hennessy carried strong evaluations from scouts due to his combination of strength, mobility, and football intelligence.

While his career has primarily unfolded as a rotational lineman rather than a long-term starter, his background as a highly rated prospect still adds intrigue to Dallas’ decision to sign him.

Cowboys Offensive Line Remains a Strength

Strong offensive line play has long been a defining trait of the Cowboys’ identity. For decades, Dallas has built its offense around dominant line play that supports both the running game and pass protection.

However, the unit showed some signs of decline during the 2025 season.

According to Nick Eatman of DallasCowboys.com, the offensive line was solid but did not quite meet the franchise’s historically high standards.

“While the 2025 season wasn’t a bad one by any means, it didn’t exactly meet the lofty standards we’ve seen in the past,” Eatman wrote in a season review.

Still, Dallas’ offensive front remained among the better units in the league.

Cowboys Ranked Among NFL’s Top Offensive Lines

Despite some inconsistencies, the Cowboys’ offensive line still finished sixth overall in the NFL in the final rankings compiled by Pro Football Network.

The group received a team grade of 80.3, placing them firmly within the league’s upper tier.

Maintaining that level of performance requires depth, especially given how physically demanding the position can be throughout a full season.

Adding a veteran like Hennessy helps ensure the Cowboys remain prepared if injuries or lineup changes occur during the year.

What the Signing Means Moving Forward

The addition of Matt Hennessy may not dramatically alter the Cowboys’ starting lineup, but it represents an important step in building reliable roster depth.

As free agency continues, Dallas appears focused on making smart, calculated moves that reinforce key positions without overspending.

For Hennessy, the opportunity provides a chance to compete for playing time with one of the NFL’s most recognizable franchises. For the Cowboys, it adds a durable and experienced interior lineman who can contribute whenever needed.

While the move may fly under the radar compared to bigger free-agent signings, it could prove valuable over the course of a long and demanding NFL season.
