Bo Ryan, the winningest coach in Wisconsin basketball history, announced his retirement late Tuesday after a 64-49 win over Texas A&M-Corpus Christi.

Ryan's retirement is effectively immediately.

"I'll see you down the road," Ryan said at the conclusion of a press conference.

Assistant Greg Gard has been named Wisconsin's interim coach.

Ryan finishes his career with 747 victories and 223 losses. The 67-year-old Hall of Fame nominee never missed the NCAA Tournament in 14 seasons as Wisconsin's head coach. He never finished worse than fourth in the Big Ten standings.

Ryan made the Final Four each of the past two seasons.

"Thanks for everything over the years, Coach Ryan," tweeted Wisconsin great Devin Harris, the fifth overall pick of the 2004 NBA Draft. "Enjoy retirement. You deserve it."

Ryan initially implied he'd retire after the 2015-16 season and that he wanted Gard to succeed him. But sources told CBS Sports that Wisconsin AD Barry Alvarez would never guarantee Gard that opportunity, which led to Ryan publicly stating he no longer knew when he'd retire. Alvarez and Ryan were never again on the so-called same page.

>>Duke Blasts Georgia Southern

Brandon Ingram had season highs of 26 points and 14 rebounds, leading No. 7 Duke to a 99-65 victory over Georgia Southern.

Grayson Allen added 18 points, Matt Jones had 16 and Derryck Thornton finished with 15 for the Blue Devils (9-1) in their first game without high-energy forward Amile Jefferson.

Coach Mike Krzyzewski said after the game that Jefferson, who averages a double-double, broke his right foot during practice and is out indefinitely, but does not need surgery.

The Blue Devils shot 57.6 percent in the second half and held a 55-29 rebounding advantage.

Tookie Brown scored 20 points and Mike Hughes added 14 for Georgia Southern (3-5), which has lost two straight and five of seven.

Duke plays Utah on Saturday in New York.
