AMES, Iowa (AP) — Senior Matt Thomas scored 25 points and No. 24 Iowa State held off a furious challenge from Oklahoma State on Tuesday night, winning 86-83 to close out its home schedule with its sixth straight win. Monte Morris added 12 points, 11 assists and nine rebounds for the Cyclones (20-9, 12-5 Big 12), who clinched their sixth consecutive 20-win season and swept the Cowboys for the fourth straight year.

Evans scored 29 points and Leyton Hammonds had 19 to lead Oklahoma State (20-10, 9-8), which lost for just the second time in 12 games. Morris forced a turnover under his own basket with 7.7 seconds left and Oklahoma State looking for a game-tying 3 — and Thomas hit an easy layup off Morris’ inbounds pass. Oklahoma State’s Juwan Evans then hit a 3, but Donovan Jackson hit a free throw and Evans couldn’t get a desperation heave off before the buzzer.

Evans made Iowa State sweat it out though. He was fouled from 3-point range with 13.8 seconds to go and the Cowboys down four. Evans hit all three from the line, but Naz Mitrou-Long answered with two free throws to make it 83-80 5 seconds later.

KANSAS CITY, Mo. (AP) – The Chiefs have released four-time Pro Bowl running back Jamaal Charles, clearing more than $6 million in salary cap space, a person familiar with the move tells The Associated Press.

The person spoke on condition of anonymity Tuesday because the move had not been announced.

Charles missed the start of last season after having surgery to repair a second torn ACL. He returned to play in three games, carrying 12 times for 40 yards with a touchdown, before having additional surgery on his knees forced him to miss the rest of the year.

The Chiefs needed to release Charles to create salary cap space to sign safety Eric Berry and guard Laurent Duvernay-Tardif to contract extensions. Berry was finalizing a $78 million, six-year deal, and Duvernary-Tardif signed a $41.25 million, five-year contract.

KANSAS CITY, Mo. (AP) – The Chiefs have signed offensive guard Laurent Duvernay-Tardif to a five-year contract extension, locking up the former sixth-round pick before he reaches free agency next season. Terms of the contract announced Tuesday weren’t revealed, but the deal is believed to be worth $41.25 million, with $20 million guaranteed. That would make him one of the highest-paid offensive guards in the NFL.

Duvernay-Tardif was the 200th overall selection out of McGill University in Canada, and he arrived in Kansas City as a raw prospect brimming with potential. The 6-foot-5, 320-pound medical student quickly earned his way into the starting lineup, and has played 30 games with 27 starts over three seasons.

He started all but two games last season, when Kansas City won the AFC West.

DES MOINES, Iowa (AP) — Drake stopped short of handing interim coach Jeff Rutter the job permanently on Monday, saying in a statement that it’ll conduct a nationwide search and that Rutter is “a strong candidate.” Athletic director Sandy Hatfield-Clubb says the Bulldogs are seeking a coach who will develop the program into one that competes for Missouri Valley Conference championships and NCAA Tournament appearances. Drake has made just one NCAA Tournament since 1971.
