Landon Donovan will not play for the U.S. national team in two upcoming World Cup qualifying matches because of an injured left knee, adding to what will be a pressure-filled few days for the Americans.

U.S. Soccer said Tuesday that Donovan -- who has more goals, assists and starts than any player in program history -- will likely not be replaced on what was a 24-man roster for the upcoming qualifiers, first on Friday on the road against Antigua and Barbuda, then in Kansas City on Oct. 16 against Guatemala.

Donovan was injured while playing Saturday for the Los Angeles Galaxy. He was selected by U.S. coach Jurgen Klinsmann for these qualifiers anyway, and the team's athletic trainers wanted him to be evaluated one more time before he started training.

Donovan had scrapped plans for an MRI in Los Angeles on Monday because he thought his knee had improved.

"Landon was very optimistic over the weekend when his knee was feeling much better, but now he needs time to recover," Klinsmann said.

Both the national team and the Galaxy said Donovan was returning to Los Angeles for further evaluation.

Colleges

The NCAA banned the Texas Southern football and men's basketball teams from the postseason, saying it came close to levying the so-called "death penalty" against the school for repeated rules violations and for lying about imposing sanctions on its own.

The Division I Infractions Committee said it found a lack of institutional control and outlined problems spanning 13 sports over a seven-year period, including booster-related recruiting violations, academic improprieties, the use of ineligible athletes and exceeding scholarship limits. The basketball team was banned from the 2012-13 postseason and the football team in 2013 and 2014.

  • The Western Athletic Conference is adding Cal State-Bakersfield and Utah Valley next year as it punts away a half-century of football. The WAC is the first Division I conference to give up football since the Southwest Conference dissolved in 1995.

  • Suspended TCU quarterback Casey Pachall is leaving school for the rest of the semester and entering an inpatient rehabilitation facility. Coach Gary Patterson made the announcement Tuesday, five days after the junior starter was arrested on suspicion of drunken driving in his second brush with the law in the past eight months.

  • Tennessee football coach Derek Dooley is recovering from surgery on his fractured right hip and will coach from the press box Saturday at No. 19 Mississippi State.

  • Florida coach Billy Donovan's oldest son, also named Billy Donovan, has transferred to Florida from Catholic University. The walk-on junior guard must sit out this season under NCAA transfer rules and will be eligible to compete for the Gators next fall.

    Golf

    The anticipated matchup between Rory McIlroy and Tiger Woods on Wednesday might not count for much after both lost their opening matches at the eight-player World Golf Finals in Antalya, Turkey.

    McIlroy lost to Matt Kuchar by six shots and Woods fell to Charl Schwartzel by one shot in the $5.2 million event. In the other group of the medal match-play format, Lee Westwood beat Webb Simpson by one shot and Justin Rose defeated Hunter Mahan by four strokes.

    NBA

    Center Dwight Howard has been cleared for limited five-on-five scrimmages with the Los Angeles Lakers in his latest step back from offseason back surgery.

    Tennis

    Rafael Nadal, in rehabilitation from a left knee injury, said he has been more encouraged recently about his progress and hopes to resume practice soon. He didn't rule out playing next month in the ATP World Tour Finals or Davis Cup final but added that such a quick return would be difficult.

    Boxing

    The Nevada State Athletic Commission has temporarily suspended Julio Cesar Chavez Jr. after the former middleweight champion failed a drug test. The commission made the standard procedural move. Chavez tested positive for marijuana use last month.
