Saturday, Oct. 20

(6) LSU at (20) Texas A&M

Kyle Field, College Station, Tex. ; 12 p.m. on ESPN
Sixth-ranked LSU (6-1, SEC: 2-1) tries to maintain momentum after handing South Carolina its first loss last week. The Tigers must find a way to stop quarterback Johnny Manziel and an Aggies' offense that put up 59 points in a win over a ranked Louisiana Tech team last week. Twentieth-ranked Texas A&M (5-1, SEC: 2-1) will try to confuse LSU quarterback Zach Mettenberger, who has struggled at times in 2012.

(9) South Carolina at (3) Florida

Ben Hill Griffin Stadium, Gainesville, Fla. ; 3:30 p.m. on CBS
Coming off its first loss of the season last week to LSU, ninth-ranked South Carolina (6-1, SEC: 4-1) doesn't get a break. The Gamecocks hope star running back Marcus Lattimore will recover from a bruised hip fast enough to play against the Gators. Third-ranked Florida (6-0, SEC: 5-0) is led by quarterback Jeff Driskel, who must be mindful of South Carolina All-American candidate Jadeveon Clowney.

(4) Kansas St. at (17) West Virginia

Mountaineer Field, Morgantown, WV; 7 p.m. on Fox
If No. 17 West Virginia (5-1, Big 12: 2-1) hadn't been upset by Texas Tech last week, this would have been a battle of Top 10 teams. The Mountaineers are led by quarterback Geno Smith on offense, but it's their defense that has been shaky. Fourth-ranked Kansas St. (6-0, Big 12: 3-0) hopes that quarterback Collin Klein can pile up yardage to help give the Wildcats the victory.

Danny Garcia vs. Erik Morales

Barclay Center; Brooklyn, N.Y. 8 p.m. on Showtime
Undefeated junior welterweight champ Danny Garcia will fight challenger Erik Morales with the Ring, WBC and WBA titles at stake. The fight is a rematch of their March bout, which Garcia won by unanimous decision.


Sunday, Oct. 21

Baltimore Ravens at Houston Texans — 1 PM

Reliant Stadium, Houston; 1 p.m. on CBS
Baltimore (5-1) has been fueled by its offense instead of its defense thus far this season. Ravens' quarterback Joe Flacco and running back Ray Rice will face a Texans' defense that looked lost against the Packers last week. Running back Arian Foster leads the Houston (5-1) offense against a Baltimore defense that will be missing linebacker Ray Lewis and cornerback Lardarius Webb, both of whom are out for the season with injuries.

Hollywood Casino 400

Kansas Speedway, Kansas City, Kan.; 2:16 p.m. on ESPN
The Chase for the NASCAR Sprint Cup is down to its last five races. Driver Brad Keselowski is in first place in the Sprint Cup standings, while second-ranked Jimmie Johnson, who won this race in 2011, trails by just seven points. Third-ranked Denny Hamlin is 15 points out of the lead.

The loser of Friday's Game 3 will be facing elimination as the two best teams in the WNBA meet to decide a champion.

Pittsburgh Steelers at Cincinnati Bengals

Paul Brown Stadium, Cincinnati; 8:20 p.m. on NBC
Pittsburgh (2-3) operates its offense through quarterback Ben Roethlisberger, who must avoid a Bengals' defense that ranks second in the league with 20 sacks. Receiver A.J. Green is the offensive star for Cincinnati (3-3). He must find ways to contribute against a Steelers' pass defense that ranks fourth in the NFL.
