The Dallas Cowboys enter their Week 4 matchup against the Houston Texans with two confirmed absences on defense. Cornerback Cobie Durant and linebacker DeMarvion Overshown have been ruled out after hamstring injuries prevented both players from practicing throughout the week.
Their availability never improved on the final report. Both were listed as nonparticipants Wednesday, Thursday and Friday, leaving Dallas to prepare without them.
The remaining names on the supplied report offer a more encouraging picture. Safety Malik Hooker, outside linebacker James Houston and cornerback Shavon Revel Jr. all finished Friday as full participants. None has a specified game designation, although that should not be confused with confirmation of their game participation.
Durant and Overshown ruled out

Durant's absence removes an option from the Cowboys' cornerback rotation. Whatever coverage combinations Dallas chooses, the available defensive backs will have to absorb the work that otherwise could have gone to him.
That matters beyond replacing one player. Losing a cornerback can reduce flexibility when a defense needs additional coverage personnel, particularly on passing downs. Dallas must organize its matchups around the players available rather than count on Durant recovering in time.
Overshown faces the same outcome after missing all three practices with his own hamstring problem. The report provides no timetable for his return, so the focus remains on how Dallas handles this game without him.
At linebacker, the challenge is maintaining communication and assignment discipline while redistributing responsibilities. Injuries do not automatically dictate how a defense will perform, but they can place greater demands on the remaining players to execute consistently.
Neither absence should be treated as a surprise after Friday's update. With both players officially out, the Cowboys can finalize their preparation knowing those two options will not be available.
Hooker and Revel finish strong
Hooker's progression was one of the more positive developments on the report. The safety was limited Wednesday and Thursday because of a forearm injury before advancing to full participation Friday.
That improvement gives Dallas a better outlook than it had earlier in the week. His game status is listed as unspecified in the supplied information, rather than carrying an out, doubtful or questionable label.
Revel followed a different path but reached the same Friday practice designation. Listed with knee and ankle injuries, he did not participate Wednesday or Thursday before returning as a full participant in the final session.
His return is relevant with Durant unavailable. It gives the Cowboys a more encouraging practice update at cornerback, although the report alone does not establish Revel's expected workload or place in the game plan.
Houston maintains full participation
Houston's shoulder injury did not produce any practice restrictions on the report. The outside linebacker participated fully Wednesday, Thursday and Friday and also has no specified game designation.
His availability contrasts with the interrupted weeks experienced by Hooker and Revel. From a preparation standpoint, three full sessions offer a steadier picture than a late return after missed practices.
Overall, Dallas heads into the matchup with a mixed defensive outlook: two players definitively sidelined and three others finishing the week without practice limitations. The encouraging Friday developments do not erase the losses of Durant and Overshown, but they prevent the supplied report from presenting a broader list of confirmed absences.
The Cowboys' priority now is turning that available personnel into disciplined execution, particularly in coverage and communication, without asking the injury report to promise more than it reveals.
