WACO, Texas -- Oklahoma defensive lineman Ronnell Lewis went down and clutched his knee on a 55-yard catch-and-run from Kendall Wright in the second quarter.

He won't be back.

Lewis is on Oklahoma's sidelines in street clothes and a knee brace. That's a big loss for the Sooners. Frank Alexander has been Oklahoma's best defender this year, but Lewis is a close second. Both are in contention for the Big 12 Defensive Player of the Year.

The Sooners defense will need to play well without him, too. Baylor scored on an unbelievable 87-yard play that caromed off Tevin Reese and floated right to a wide-open Kendall Wright in stride downfield, tying the score at 24.

You won't see that too often, but the Sooners had a similar touchdown pass to Jermaine Gresham against Oklahoma State back in 2008.
