Here are things you’ll want to know about the game when No. 3 Ohio State (7-1, 5-0) goes on the road against Iowa (5-3, 2-3):

1. Kickoff is at 3:30 p.m. Saturday in Kinnick Stadium (capacity 70,585) in Iowa City. Expect cloudy skies and a game-time temperature around 50.

2. Iowa has declared this a "blackout" game, and the team will wear alternate uniforms that feature black helmets, black pants and black jerseys with numbers outlined in gold. Fans also have been encouraged to wear black for the game.

3. Oddsmakers have Ohio State favored by 18 points over the Hawkeyes, who have only one victory over the Buckeyes in their last 14 meetings going back to 1991. That was a 33-7 win in 2004 at Kinnick Stadium.

4. The game is being televised by ESPN, whose crew will be Steve Levy (play-by-play), Brian Griese (analysis) and Todd McShay (sideline).

5. You also can hear the game on local radio at 97.1 The Fan with announcers Paul Keels (play-by-play), Jim Lachey (analysis) and Matt Andrews (sideline).

6. Be sure to stick with the broadcast at the end of the first quarter and you will see the best new tradition in college football. This season, everyone in Kinnick stadium takes a moment to wave at the kids looking down from the adjacent Stead Family Children's Hospital. "The Wave," as it is known, began earlier this year, but the Iowa football program has a long history of supporting and visiting the hospital. Iowa coach Kirk Ferentz and his wife, Mary, have committed $1 million to the hospital to support research to help premature babies.

7. Running back J.K. Dobbins has 863 yards in eight games, and he's on pace to become just the fourth Ohio State freshman to gain more than 1,000 yards rushing. Can you name the other three? The answer is at the bottom.

8. Expect to hear a lot about ... quarterback Nate Stanley, who has passed for 1,703 yards and 17 touchdowns ... receiver Nick Easley, who has 36 catches for 375 yards and four touchdowns ... and senior linebacker Josey Jewell, who has 81 total tackles and leads the Big Ten in average tackles per game.

9. Strength vs. strength: Iowa ranks No. 12 in the nation in scoring defense, allowing just 17.4 points per game, while Ohio State ranks No. 2 nationally in scoring offense at 46.3 points per game.

10. Ohio State center Billy Price, who has already graduated, will make his 50th consecutive start, tying the school record set by Luke Fickell in 1993-96. Price has been named a first-team mid-season All-American by the Associated Press, and he's on the watch list for the Rimington Trophy, given to the nation's best center. (It went to OSU's Pat Elflein last year.)
