NEW YORK — Yankees shortstop Derek Jeter says he will retire after this season “with absolutely no regrets,” ending one of the greatest careers in the history of baseball's most storied franchise.

The 39-year-old New York captain posted a long letter on his Facebook page Wednesday saying that 2014 will be his final year.

A 13-time All-Star who has led the Yankees to five World Series championships, Jeter was limited to 17 games last season while trying to recover from a broken left ankle sustained during the 2012 playoffs.

“I know it in my heart. The 2014 season will be my last year playing professional baseball,” he wrote.

Dolphins offensive lineman Richie Incognito lashed out at teammate Jonathan Martin on Twitter Wednesday, saying “The truth is going to bury you and your entire `camp.' You could have told the truth the entire time.”Incognito's series of tweets directed at Martin and his representatives come as the NFL is preparing to release a report on the Dolphins' bullying case which could help clarify their much-publicized relationship.

A proposed change by the NCAA football rules committee would prohibit offenses from snapping the ball until at least 10 seconds had run off the 40-second play clock, slowing the up-tempo, no-huddle attacks that have been making defenses dizzy.The rule allows defenses time to make a substitution without the offense changing players — as is currently required — and with no fear the ball will be snapped before 29 seconds are left on the play clock. An exception will be made for the final two minutes of each half.Duke, North Carolina game postponedThe winter storm and icy conditions moving through the South caused teams to postpone games scheduled for this week, including Wednesday night's showdown between No. 8 Duke and North Carolina.
