Matt Painter has rejected a contract offer from Missouri and decided to remain at Purdue thanks to a new and extended contract that has been agreed upon in principle, a source told CBSSports.com on Wednesday.

An official announcement is expected soon.

Painter's decision to remain at his alma mater ends a wild few days on the coaching carousel during which Purdue and Missouri both made very public pleas -- Purdue to try to keep him, Missouri to try to take him -- for the man who has been named Big Ten Coach of the Year in three of the past four seasons. Despite those honors -- and five straight NCAA tournament appearances -- Purdue had been paying Painter only $1.3 million annually. That number ranks eighth in the Big Ten and is among the reasons Missouri believed he could be lured from the place where he was tabbed as Gene Keady's replacement before Keady retired in 2005.

Details of Painter's new deal are unclear, but he will receive a significant raise. His staff will also receive notable pay increases and be afforded a budget to operate like a true high-major program, something that was never the case in Painter's first six seasons with the Boilermakers.

Missouri's search for a new coach will now move on to secondary candidates.

Mike Anderson left Missouri for Arkansas last week.

Florida assistant Larry Shyatt is interviewing with Wyoming and could be introduced as the Cowboys' next head coach in the next 48 hours, a source told CBSSports.com on Wednesday.

Assuming Shyatt gets the job, it'll be his second stint as head coach of the Cowboys. He led the school to a 19-9 record in the 1997-98 season, then took the Clemson job when Rick Barnes left the ACC for Texas. Shyatt was the head coach at Clemson from 1998 to 2003.  He's been on Billy Donovan's staff since 2004 and was instrumental in Florida's back-to-back national championships in 2006 and 2007.

Wyoming fired Heath Schroyer last month.

Louisiana Tech, as expected, hired Ole Miss assistant Michael White to be its next men's basketball coach on Tuesday, a source told CBSSports.com.

A formal announcement is expected soon.

White is a New Orleans native who played at Ole Miss and has spent the past seven years as an assistant in the program -- first for Rod Barnes, then for Andy Kennedy. White replaces Kerry Rupp, who was fired earlier this month after four seasons that featured a 20-44 record in the WAC.

Jim Burr, the controversial referee who has worked 16 Final Fours and seven national title games, will not work Saturday's national semifinals or Monday's national title game in Houston, a source told CBSSports.com on Tuesday.

A source said the 10 preselected officials with Final Four assignments are:

• John Cahill
• Pat Driscoll
• Verne Harris
• John Higgins
• Les Jones
• Jamie Luckie
• Antinio Petty
• Doug Shows
• Michael Stephens
• Mark Whitehead

Burr has been criticized in recent weeks for the way he handled the end of the St. John's-Rutgers game during the Big East tournament, and for a questionable non-call in Arizona's win over Memphis in the Round of 64 of the NCAA tournament. Burr's last game was Arizona's win over Texas in the Round of 32.

Memphis officials have reached a deal on a five-year contract extension for men's basketball coach Josh Pastner, a source told CBSSports.com early Tuesday.

The school subsequently confirmed the CBSSports.com report.

Pastner's new contract is worth $1.7 million annually.

"We are delighted that Coach Pastner has accepted our contract offer and will remain as our basketball coach for years to come,” said Memphis athletic director R.C. Johnson. “He is, without a doubt, one of the most exciting young coaches in the country, and we anticipate continued growth for our basketball program."

Pastner had been linked to openings at N.C. State, Missouri and Oklahoma in recent days. He just took Memphis to the NCAA tournament and should return a preseason Top 25 team next season headlined by Will Barton, Joe Jackson, Tarik Black and incoming freshman Adonis Thomas, a McDonald's All-American from Melrose High in Memphis

"I have stated numerous times that the Memphis basketball job is one of the top five jobs in the country,” Pastner said. “I am most appreciative of the opportunity and understand the responsibility I was presented by R.C. Johnson to coach this team. We have everything we need to be successful and build championship caliber teams. From a modern arena, to a great practice facility, to one of the strongest fan bases in the nation, to an outstanding recruiting area, Tiger basketball is one of the top five programs in the country and should always remain at that elite level."

Pastner is 49-20 in two years with the Tigers.

He replaced John Calipari in April 2009.

Ole Miss assistant Michael White is on the Louisiana Tech campus for the second straight day and, barring an unexpected breakdown in negotiations, is expected to be named the Bulldogs' next head coach, multiple sources told CBSSports.com on Tuesday.

The move should be official later this week.

White is a New Orleans native who played at Ole Miss and has spent the past seven years as an assistant in the program -- first for Rod Barnes, then for Andy Kennedy. White replaces Kerry Rupp, who was fired earlier this month after four seasons that featured a 20-44 record in the WAC.

Pittsburgh standout Ashton Gibbs will declare for the NBA Draft but will not hire an agent, a source told CBSSports.com on Tuesday.

Gibbs averaged 16.8 points and shot 49.0 percent from 3-point range this season.

The 6-foot-2 guard is not projected as a first-round pick.

Gibbs can withdraw from the draft by the May 8 deadline and return to Pittsburgh as long as he maintains his amateur status. A source close to Gibbs told CBSSports.com that Gibbs returning for his senior year remains the most likely scenario given his uncertain draft status.

"I think he just wants to get some workouts in with NBA teams," the source said.

The deadline for underclassmen to declare for the draft is April 24.

Purdue coach Matt Painter will meet with Missouri officials over the next 48 hours about the school's vacant head coaching position, according to a report in the St. Louis Post-Dispatch.

It is believed that Missouri could offer Painter a contract worth more than $2 million annually. Purdue only pays Painter around $1.3 million a year -- though he'll make around $1.9 million this year because of bonuses earned during this 25-win season, according to the Indianapolis Star. Still, Painter's base salary ranks in the bottom half of the Big Ten.

"Matt wants a situation where he will be able to make a run for a national championship," former Purdue coach Gene Keady told CBSSports.com on Monday. "The administration here has to step up and help him."

That said, Keady added this: "I think he'll stay."

Painter has led Purdue to five straight NCAA tournament appearances and two Sweet 16s in six total seasons. Purdue has finished in the top two of the Big Ten in each of the past four seasons.

Missouri is looking for a coach to replace Mike Anderson.

Anderson left for Arkansas last week.
