DETROIT — Preston Stone threw three touchdown passes and Northwestern turned four turnovers into touchdowns and beat Central Michigan in the GameAbove Sports Bowl at Ford Field.

The Wildcats (7-6) extended their bowl game winning streak to six. They haven’t lost in the postseason since a 45-6 loss to Pittsburgh in the 2015 Outback Bowl.

Central Michigan (7-6) is 0-3 against the Big Ten in bowl games, with all three losses coming at Ford Field. The Chippewas lost 51-48 to Purdue in the 2007 Motor City Bowl and 21-14 to Minnesota in the 2015 Quick Lane Bowl.

Central Michigan had the first scoring opportunity of the game after stopping Northwestern on 4th-and-1 at the Wildcats 34, but Cade Graham missed a 43-yard field goal attempt.

The game was still scoreless midway through the second quarter, but Braden Turner intercepted Angel Flores’ pass at the Central Michigan 29. Three plays later, Stone threw a 23-yard touchdown pass to Griffin Wilde to give the Wildcats a 7-0 lead.

Kittle dealing with bad ankle

SANTA CLARA, Calif. — San Francisco star tight end George Kittle was listed as questionable with an ankle injury for the 49ers’ key game in playoff positioning on Sunday night against the Chicago Bears.

Kittle missed the full week of practice after getting hurt Monday night in a win against Indianapolis. But coach Kyle Shanahan said Friday that he still has a chance to play with the team having a better idea of his status closer to the game.

Receiver Ricky Pearsall is also questionable after missing last week’s game and being limited all week in practice by a knee injury. Cornerback Renardo Green will miss a second straight week with a neck injury.

The 49ers (11-4) clinched a playoff spot last week but are still in the hunt for a division title and possibly the top seed in the NFC playoffs. With wins at home over Chicago (11-4) and Seattle (12-3) the next two weeks, the Niners would clinch home-field advantage and would have a chance to win the Super Bowl on their home field Feb. 8 without having to take another road trip all season.

Being without Kittle would be a big blow to a San Francisco offense that has been operating at a high level during a five-game winning streak. The Niners have gone back-to-back games without having to punt for the first time in franchise history.

Crosby out for Raiders

HENDERSON, Nev. — The Las Vegas Raiders have decided to bench defensive end Maxx Crosby for Sunday’s home game against the New York Giants in a matchup of teams with the NFL’s worst records.

The loser has the inside track to the top overall draft pick, and the Raiders will be resting other key players this week.

Tight end Brock Bowers (knee) and safety Jeremy Chinn (back) were placed on season-ending injured reserve on Wednesday. Bowers is a two-time Pro Bowler who earned first-team All-Pro honors last season.

Crosby has a knee injury that has led to him missing numerous practices this season, but he has started every game. Crosby left the team facility after the Raiders informed him of the decision.

“After an evaluation we did Monday or Tuesday, it just looks too bad,” coach Pete Carroll said Friday. “He didn’t want to take the news like that and I didn’t want to take the news like that, so we worked our way through to get to this point. He’s been practicing on Fridays. If we had let him, he would’ve gone out there and he would not have hesitated, but he knows that he’s banged up.”

Carroll said he expected Crosby’s negative reaction to the decision.
