Steelers-Chiefs game has time change

The AFC divisional playoff game between the Steelers and Chiefs on Sunday has been moved from an early afternoon kickoff to primetime because of an ice storm due to hit the Kansas City area this weekend.

The game was originally scheduled to kickoff at 1:05 p.m. It will now start at 8:20 to give road crews and public safety officials more time to treat roads and parking lots.

"If people are going to the game, slow down, leave early and be cautious," said Troy Schulte, the city manager for Kansas City, Missouri, where Arrowhead Stadium sits just off Interstate 70.

The forecast calls for ice to move into the area Friday, and persistent cold temperatures throughout Saturday and Sunday. More precipitation is expected Sunday, though mostly in the form of cold rain.

The time change means the Packers-Cowboys game scheduled to kickoff at 4:40 p.m. on Fox on Sunday will serve as the lead-in for the Steelers-Chiefs game, which will remain on NBC.

Packers' Nelson won't play

Receiver Jordy Nelson will miss Green Bay's divisional round playoff game on Sunday against the Dallas Cowboys because of injured ribs.

Coach Mike McCarthy said Friday that Nelson would not be cleared to take part in the team's final practice on Saturday, and the medical staff determined he would not be ready for the game.

Nelson had an NFL-high 14 touchdown catches in the regular season as quarterback Aaron Rodgers' top target in the Packers' prolific passing attack. He was hurt in the second quarter of the Packers' 38-13 win in a wild-card game last weekend against the New York Giants during a hit by safety Leon Hall.

Team doctors "don't feel — frankly they just would not medically clear him for Sunday," McCarthy said Friday.

Randall Cobb returned last week from an ankle injury and caught three touchdowns, including a 42-yard score on a Hail Mary pass. Davante Adams has emerged as a playmaker in his third NFL season with 12 touchdown catches.

Undrafted rookie free agent Geronimo Allison stepped up in Cobb's two-game absence at the end of the regular season with eight catches for 157 yards and a touchdown. Jared Cook has given Rodgers an athletic target at tight end that the Packers haven't had the last couple seasons.

"Well, we feel we have playmakers at a number of different positions and I think we'll certainly create opportunities," offensive coordinator Edgar Bennett said Thursday about the possibility of not having Nelson. "It's always about matchups and we're excited to have the opportunity to go into Dallas this week."

Mike Smith stays with Bucs 

Mike Smith says he's committed to helping the Tampa Bay Buccaneers realize their potential, not trying to become a head coach again.

The Bucs signed their defensive coordinator to a contract extension on Friday, ending speculation about where the former Falcons coach might wind up next season.

Smith spoke with the Jaguars and the Chargers about head coaching vacancies this winter after an improved Bucs' defense led a turnaround that produced Tampa Bay's first winning record in six years.

Smith said he's excited about the direction of the Bucs under coach Dirk Koetter, who hired his former boss last winter. He looks forward to building on the success of the past season.

"While I did have a chance to speak with a few organizations about head coaching opportunities earlier this offseason, it became very clear to me that I am in an ideal situation here with the Buccaneers," Smith said. "For the next couple years, I am fully committed and focused on my role with Dirk and the organization and will not be pursuing head coaching opportunities during this time."

Ex-Ravens president David Modell dies 

David Modell, the first president of the Baltimore Ravens and the son of former team owner Arthur Modell, died Friday. He was 55.

He had cancer for two years, the team said.

Modell served as president of the Ravens from their beginning in 1996 until 2004. He was instrumental in the selection of the team's name and colors and helped orchestrate the move to the Ravens' new stadium in 1998.

Modell and his father worked in tandem to make sure the team flourished following its relocation from Cleveland in 1995. The younger Modell's focus was not only to make the Ravens a winner, but to do it with class.

Modell played a role in hiring coach Brian Billick, who led Baltimore to a Super Bowl victory in 2000.

Billick on Friday said Modell was "at the very core of our success with the Ravens."

David Modell's connection with the team ended soon after Art Modell sold the Ravens to Steve Bisciotti in 2004.

Modell is survived by his wife, Michel, and their 2-year-old twins, Aoife and Bertram. He had four children from his first marriage: daughters Breslin and Collier and sons Arthur and David Jr.
