In what was the most significant win for the Big 12 Conference, as a whole, No. 5 Oklahoma dominated No. 2 Ohio State in a 31-16 road victory last Saturday.

The triumph was one of two significant wins for the Big 12, which also had TCU defeat Arkansas 28-7 in Fayetteville, Ark.

While both wins were compelling in their own rights, Oklahoma head coach Lincoln Riley was quick to temper some of the high praise his program was beginning to receive following the upset win.

"We’ve got to keep our goals in perspective and know that we haven’t reached any of those yet," said Riley, whose team jumped to No. 2 in the latest AP football poll. "We’ve still got a long ways to go. We’re only two games into the season and to be where we want to be in the end, we’ve got to get a lot better."

And while the victory was enough to fill the headlines in itself, the Sooners had another piece of news out of Columbus, Ohio.

After throwing for 386 yards and three touchdowns, to improve his Heisman Trophy résumé, Mayfield grabbed and Oklahoma flag, celebrated the win around the stadium before he stuck it inside the Block O at midfield. His actions received positive and negative reviews nationally.

The senior quarterback, who was named the Big 12 Offensive Player of the Week for the second straight week, apologized for his actions during a Monday press conference.

"It was an emotional game," Mayfield said. "So, after the game, I did not mean it to be disrespectful toward any Ohio State people at all — especially not the team or players. Because they’re a great team and a great program. … It should have been something I did in the locker room. So, I apologize for doing it in the middle of the field."

The Horned Frogs showed plenty of physicality on the field in their win over the Razorbacks.

In the most telling statistic from the game, TCU won the time of possession 33:52 to 26:08 and stole valuable offensive possessions away from Arkansas.

On the other side of the football, the Horned Frogs defense played stout by yielding only 267 yards of total offense — one week after giving up 65 total yards in a 63-0 win over Jackson State.

Over the last two games, No. 20 TCU has allowed seven points and 332 yards.

OU injury update

Due to an apparent left knee injury, Mark Andrews did not make much of an impact in the Sooners win over the Buckeyes.

But the Oklahoma tight end, who left early in the second quarter and did not return to the field against Ohio State, is hoping to change that this week.

Riley expects Andrews to play when the Sooners host Tulane at 5 p.m. Saturday.

"Mark’s good," Riley said. "We think Mark will play this week. He’s doing well, improving quickly."

Left guard Cody Ford and safety Will Johnson were listed as day-to-day, Riley said during a Monday press conference.

Baylor QB change

Zach Smith is scheduled to start under center for the Bears in their first road game against Duke this weekend.

Smith, a sophomore signal caller, is replacing graduate transfer Anu Solomon who earned the starting nod in Baylor’s first two games — both losses. Solomon, who transferred from Arizona, has thrown for 399 yards, four touchdowns and two interceptions.

As a freshman, Smith started in the final four games.

After dropping the first three contest, he led the Bears to a 31-12 victory over Boise State in the Cactus Bowl last season. Smith played through an ankle injury and threw for 375 yards and three touchdowns on 28 of 39 passing.

"We’re going to turn to Zach and let him do his thing," said Baylor coach Matt Rhule on Monday. "We’ll rally around Zach. He’s a competitor, you know. Anu got banged up a little bit in the game and Zach is ready to go. He’s healthy now. I think that ankle’s 100 percent. He’s moving around well."

Setting records

Even in a loss, Peyton Bender found a way to put a positive twist.

The junior quarterback, who threw for 323 yards and two interceptions in the 45-27 loss to Central Michigan over the weekend, broke a school record that dated back 44 years.

After completing 32 of his 62 passes, Bender notched the most passing attempts by a Jayhawks quarterback since David Jaynes threw 58 back in 1973.

OSU playing on weekend

For the first time this season, the No. 9 Cowboys will play on Saturday.

In its first two games of the year, Oklahoma State played Thursday (Tulsa at home) and Friday (at South Alabama) before traveling to play Pittsburgh at 11 a.m. Saturday on ESPN at Heinz Field.

Quarterback Mason Rudolph has played stellar to say the least, throwing 28 touchdowns pass to only two interceptions in his last 11 contests. He’s also thrown 185 passes without an interception, the longest active streak in the country.
