Jim Harbaugh is not making friends in the SEC. The Michigan football coach's plan to take his team to Florida for spring break has ruffled some feathers in the conference.

SEC commissioner Greg Sankey told CBSSports.com that the SEC has asked the NCAA to prohibit teams from holding spring practice during spring break.

Because there is no rule prohibiting where a team can practice, this may be the SEC's best way to block U-M's planned trip to hold four practices at IMG Academy in Bradenton, Fla., from Feb. 28-March 4.

Harbaugh said at National Signing Day that he decided on spring break because that would allow all athletes to go, even if they couldn't afford to go on the break on their own. By the school paying for it — U-M is flying commercial to save money — it alleviates that concern.

Rebels cited for 28 violations

Mississippi's football program reportedly was cited by the NCAA in nearly half of the 28 rules violations levied against the school in the Notice of Allegations the university recently received. The report said 13 of the allegations involve the football program, and nine of those occurred during current coach Hugh Freeze's tenure.

The violations are a mix of Level I — which the NCAA considers most serious — and Level II and III. Many have already been self-reported by the school.

The school's women's basketball and track and field programs are also involved in the investigation.

Ole Miss has been under investigation since 2012 when women's basketball coach Adrian Wiggins and two assistants were fired after a school investigation found academic and recruiting misconduct. Two players were ruled ineligible and the school self-imposed a one-year postseason ban. Ole Miss has 90 days to respond to the Notice of Allegations.

Latos had consecutive 14-win seasons with Cincinnati in 2012 and 2013, but the 6-6 right-hander hasn't been able to duplicate that success in recent years. He played for the Marlins, Dodgers and Angels last season, finishing with a 4-10 record and a 4.95 ERA.

Umpires banned for corruption

The International Tennis Federation says two umpires have been banned for corruption offenses and four more are suspended.

The sanctions were concealed until being confirmed by the governing body in response to a story Tuesday in The Guardian.

The ITF says Kazakhstani Kirill Parfenov was banned for life in February 2015 for using Facebook to contact another official in an "attempt to manipulate the scoring of matches."

Denis Pitner of Croatia was suspended for a year in August after passing on details on the "physical well-being of a player to a coach during a tournament and regularly logging on to a betting account from which bets were placed on tennis matches."

The ITF didn't give any details on the matches or why four other officials were suspended while under investigation.
