Donnie Tyndall

On April 8, 2016, the NCAA imposed a 10-year show-cause penalty on Tyndall, to run until April 7, 2026 – tied for the longest ever imposed on a head coach. This means that any NCAA member school that wants to hire him during this period will have to "show cause" for why it shouldn't be sanctioned for doing so, and could incur severe penalties if he commits another violation during this time. It also stipulates that any penalties imposed on Tyndall will follow him to any NCAA member school if he is ever hired again. According to the NCAA, Tyndall told his assistants to complete papers for players, and also arranged payments to players and tried to cover them up. The NCAA deemed Tyndall's violations to be as egregious as those committed by Dave Bliss at Baylor 16 years earlier; Bliss is the only other head coach to be slapped with a 10-year show-cause. In an unprecedented move, the NCAA required any NCAA member school who hires Tyndall during his show-cause to suspend him from coaching duties--effectively banning him from coaching at any NCAA member school until the end of the 2025–26 season. This was very unusual since Tyndall would have likely found it difficult to return to the collegiate ranks in any event while his show-cause was in effect. A show-cause usually has the effect of blackballing a coach from the collegiate ranks at least for the duration of the show-cause; most schools will not even consider hiring a coach with such a severe penalty on his record. In another unusual move, the NCAA decreed that if Tyndall ever coaches again at an NCAA member school after the show-cause runs out, he must sit out the first half of the first season after his return. USA Today called it the most severe penalty that the NCAA has ever meted out to a head coach.

On November 4, 2016, Tyndall was hired by the Toronto Raptors to be an assistant coach on their development team, Raptors 905. Toronto Raptors head coach Dwane Casey was fired in May 2018 and was then hired as the head coach of the Detroit Pistons; Tyndall then took an assistant coaching role with Grand Rapids Drive, the development team for the Pistons. After one season, he was promoted to head coach of the Drive for the 2019–20 season.

On March 27, 2015, Tennessee fired Tyndall after the NCAA notified Tennessee officials of possible major violations at Southern Miss. The violations centered around improper financial aid for two players, as well as academic problems with junior college transfers. According to a copy of Tyndall's termination letter, Tyndall had lied to Tennessee officials about the extent of the violations on several occasions, and had also deleted several emails from an old email account dating to his time at Morehead State even though he was aware he would have been questioned about activity on that account by the NCAA. Athletics director Dave Hart said that in all likelihood, Tyndall would have faced significant discipline from the NCAA for his role in the violations at Southern Miss. Former coach Bruce Pearl had been slapped with an eight-game suspension during what proved to be his final season in Knoxville for major recruiting violations, and Tennessee didn't want a repeat of that experience. Hart said that he would have never hired Tyndall had the true extent of the violations at Southern Miss been known.

On April 22, 2014, Tyndall was hired as head basketball coach at the University of Tennessee, after spending the previous two seasons as the head basketball coach at Southern Miss.

* Southern Miss's original records were 27–10 (12–4, 2nd in C-USA) in 2012–13 and 29–7 (13–3, 1st in C-USA) in 2013–14. However, all 56 wins from those seasons were vacated by the NCAA due to participation of academically ineligible players.

Tyndall was the head coach at the Southern Miss from 2012 to 2014. Southern Miss made the National Invitation Tournament in 2013 and 2014 and finished first in Conference USA standings for the 2013–14 season. Tyndall went 56–17 as head coach at Southern Miss, but in 2016, the NCAA vacated all 56 wins due to academic fraud.

In August 2010, the NCAA placed Morehead State on two years' probation for violations by boosters. As a #13 seed, Morehead State upset #4 seed Louisville 62-61 in the first round of the 2011 NCAA Tournament.

In his first Division I head coaching job, Tyndall served as head coach at his alma mater Morehead State from 2006 to 2012. Morehead State under Tyndall won the Ohio Valley Conference tournaments of 2009 and 2011 and earned automatic NCAA Tournament bids those years. Morehead State also made the 2010 College Basketball Invitational.

From 2002 to 2006, Tyndall was associate head coach at Middle Tennessee under Kermit Davis. Middle Tennessee had winning seasons all four of those seasons.

In the 2001–02 season, Tyndall served as associate head coach at Idaho under Leonard Perry.

After his season at St. Catharine, Tyndall got his first NCAA Division I coaching position as an assistant at LSU under John Brady, a position he would hold from 1997 to 2001. Tyndall helped LSU finish first in the SEC West Division in the 1999–00 season and make the Sweet 16 round of the 2000 NCAA Tournament. This LSU team also featured Stromile Swift, the #2 pick in the 2000 NBA draft.

After graduating from Morehead State University in 1993, Tyndall began coaching at the junior college level. From 1994 to 1996, he was assistant coach at Iowa Central Community College. Tyndall had his first head coaching position in the 1996–97 season at St. Catharine College in Springfield, Kentucky. Tyndall led St. Catharine to a 30–5 record and the school's first-ever NJCAA tournament appearance. In 1997, Tyndall earned NJCAA Region 7 National Coach of the Year and Kentucky Junior College Coach of the Year honors.
