Oklahoma State Is Waiting On One Defensive Decision That Could Reshape Saturday

Oklahoma State faces a critical decision in preparation for the Houston game as they await updates on an injury to one of their key defensive players.

Oklahoma State heads into Wednesday night’s first player availability report with one defensive name worth watching: safety Mose Phillips III.

Phillips exited Saturday’s game against UCF with a shoulder issue, according to Cowboys Radio Network during the broadcast. He was seen with a shoulder sleeve in the second half and did get his pads back on, but he never made it back onto the field.

After the game, Cowboys head coach Eric Morris sounded optimistic when asked about Phillips. By Tuesday, he was less certain, though he still didn’t spell out the extent of the injury.

“We'll see this week how he develops with the shoulder,” Morris said. “So I don't know on Mose yet.”

Phillips wasn’t listed as a starter when the season’s initial depth chart came out, but he worked his way into the starting spot at boundary safety before the Oregon game. The senior arrived with three years of college experience, spending two seasons at Virginia Tech and one at Missouri.

His production had started to climb. Through five games, Phillips had 23 tackles - 10 solo and 13 assists - along with three passes defended. He also picked off a pass against West Virginia, a turnover that swung the game in Oklahoma State’s favor.

If Phillips can’t go, the Cowboys have a clear next man up in Evan Jackson. Jackson started the opener against Tulsa, then settled into a backup role, but he made one of the biggest plays of the UCF game with a scoop-and-score after a backward pass led to a fumble, giving Oklahoma State a 35-21 lead in the fourth quarter.

Jackson’s season numbers are modest - four tackles - but he brings familiarity with defensive coordinator Skyler Cassity’s 4-2-5 scheme. At North Texas last season, he started one game under Cassity and posted 44 tackles, including 28 solo stops, plus two interceptions and two pass break-ups.

His 2024 season was even bigger before Cassity arrived at North Texas. Jackson started nine of 13 games and finished with 55 tackles, 38 of them solo, while adding three interceptions.

That track record gives Oklahoma State a potential lift if Jackson has to take on a larger role. He’s shown he can create turnovers, and that matters for a defense that hasn’t been generating enough of them this season.

For now, the Cowboys wait on Phillips and keep Jackson ready.

Oklahoma State Faces A Bigger Test Than Just Another Big 12 Game

Eric Morris just reached the 50-win mark in his head-coaching career, a milestone worth noting even in a conference where the week-to-week pressure never really lets up. Ahead of Oklahoma States next matchup, he also took a moment to acknowledge the much longer road Willie Fritz has traveled, pointing to the Houston coachs 266 career victories and the steady climb that has defined Fritzs career.

For a Cowboys team preparing for a demanding Big 12 test, the contrast in experience adds another layer to the matchup. Morris clearly has respect for the work Fritz has put in over the years, and it frames this game as more than just another conference date on the schedule, with two programs that have both earned their way into the national conversation now measuring themselves against a coach whose rsum stands far above the rest.

Oklahoma State Faces Its Biggest Big 12 Test Yet At Houston

No. 18 Oklahoma State heads to Houston for a showdown that suddenly carries real weight in the Big 12 race, with both teams sitting inside the AP top 20 and the conference-championship picture very much in play. The trip to TDECU Stadium brings together a Cowboys team that has put together four straight wins and a Cougars group that just knocked off Kansas State, a reminder that this is not just another late-season league game.

For Oklahoma State, the bigger story has been how quickly the program has steadied itself after a major roster overhaul, with first-year coach Eric Morris guiding a group that looks far more settled than it did in the fall. Houston has its own momentum and its own offensive playmakers, so this one has the feel of a true measuring-stick game for the Cowboys, with the result likely to say plenty about where they fit in the conference hierarchy.

Oklahoma States Surprising Run Faces Its Biggest Test Yet

Oklahoma States rebound from a season-opening loss has turned into one of the more encouraging early stretches in the Big 12, with four straight wins capped by the upset of Oregon. Now the Cowboys head into a matchup with No. 20 Houston, a team that has found its footing too with three consecutive victories, setting up a game that feels like a real measuring stick rather than just another step in September.

Houston has been getting production from tight end Patrick Overmyer, who leads the Cougars in receptions and yards and comes in as one of the leagues more intriguing mismatches. For Oklahoma State, the challenge is clear: keep the momentum alive against a ranked opponent that is also in form, and do it on the road where small mistakes can quickly tilt a game like this.
