Oklahoma has fired offensive coordinator and quarterbacks coach Seth Littrell, per ESPN's Pete Thamel, who provided more information.

The 4-3 Sooners (1-3 SEC) just lost 34-3 to arch-rival Texas and 35-9 to South Carolina in back-to-back weeks. Their 22.1 points per game thus far ranks just 107th out of 134 Division I-FBS teams.

Fifty-one of the Sooners' points came in the season opener against 2-5 Temple. Oklahoma snuck by Auburn 27-21 despite being outgained 482-291, as a fourth-quarter pick-six propelled the Sooners to a win.

The Sooners also barely beat Houston 16-12 despite being outgained 318-249. One of their two touchdowns occurred after Oklahoma got a short field after recovering a fumbled Houston punt on the Cougar 10-yard line.

A 34-19 over the 5-2 Tulane Green Wave is ultimately the Sooners' most impressive result this year, but Oklahoma has gone 1-3 since. That skid started with a 25-15 loss to Tennessee.

The Sooners' passing game has struggled in particular with just 176.4 yards per game (112th overall). The run game has been even worse, with the team amassing just 3.1 yards per carry (123rd in college football).

Oklahoma was once 15th in the Associated Press poll with legitimate College Football Playoff hopes, but those have gone by the wayside after an ugly stretch. Now the Sooners hope a change in offensive leadership can boost the scoring output in the second half of the season.

But the final five regular-season games won't be easy, with matchups against four ranked SEC teams in No. 18 Ole Miss, No. 21 Missouri, No. 15 Alabama and No. 8 LSU. Up first is Ole Miss on Saturday in Oxford.
