The Dallas Cowboys got the worst possible news on Thursday. Trevon Diggs, the star cornerback and two-time Pro Bowler, suffered a season-ending injury during practice.

Where does that leave Dallas and their cornerback depth chart? The solution to losing Diggs could be as simple as moving DaRon Bland or Jourdan Lewis to take over the cornerback spot opposite Stephon Gilmore. They also have Noah Igbinoghene and Eric Scott available.

However, the internal options could also be supplemented with a free agent acquisition. Let's look at what options the Cowboys have out there.

NFL Rumors: Cowboys can add Anthony Brown to replace Trevon Diggs

The Cowboys are very familiar with Anthony Brown. The cornerback played seven seasons in Dallas, starting 72 games before he suffered a torn Achilles in Week 13 last year.

That injury is the biggest question mark around Brown's viability as an addition for the Cowboys. Brown was signed to the Steelers practice squad to start the season but the 49ers picked him up to help out their injury-hit secondary. However, San Francisco backtracked on Thursday by releasing him to promote a different DB from the practice squad.

So is Brown ready to play? That's not certain. Let's say he's not. It might still be worth bringing him in to get back up to speed in Dallas while the rest of the cornerback room fills in the gap for now. He could be a valuable addition down the line knowing Diggs will miss the rest of the season.

NFL Rumors: Cowboys can add Greedy Williams to replace Trevon Diggs

Greedy Williams may be one of the better cornerback options left on the market after being released by the Eagles in the preseason.

Williams was a second-round draft pick by the Browns in 2019. He started 21 games during four seasons in Cleveland but saw his usage taper off in 2022. He missed the whole 2020 season because of an injury and also missed time in his final season.

The injury issues gave the Browns their reason to move on from the cornerback. He tried to make it work in a crowded Eagles secondary but was a camp cut.

Health and availability have held Williams back throughout his career but his potential coming out of LSU was clear. There were bright spots in Cleveland so maybe Dallas can help him revive his career.

Williams is only 25 years old and has two interceptions, 12 pass deflections, one forced fumble and two tackles for loss in his career.

NFL Rumors: Cowboys can add Bradley Roby to replace Trevon Diggs

If the Cowboys want to add a veteran presence instead of a young guy trying to restart his career, there are plenty of options to consider. Casey Hayward would be worth a call but he ended last season on IR with a shoulder injury and was released in April after a failed physical.

Bradley Roby, on the other hand, has taken visits recently and appears to be actively searching for a new home.

Roby spent camp with the Saints but he didn't make the roster. He visited the 49ers as they searched for reinforcements for their depleted secondary.

Last year, Roby started 10 games with the Saints. He had five pass deflections, two fumble recoveries and one tackle for loss.

Roby was a productive cornerback for the Broncos from 2014 to 2018. More recently he's spent two seasons each with the Texans and Saints. He has 11 interceptions in his career.

The Cowboys could always stick with what they've got at cornerback but Roby would give them veteran experience in Diggs' absence.
