Terrell Stoglin, the leading scorer on the Maryland men’s basketball team, has been suspended for the upcoming season for violating the university’s student-athlete code of conduct. The decision prompted Stoglin to submit his name for the NBA draft.

Also suspended for one year was reserve swingman Mychal Parker, also a sophomore, who had announced April 9 that he was transferring from Maryland when faced with the prospect of diminished playing time.

Maryland officials confirmed news of the suspensions, and Stoglin’s decision to enter his name for the NBA draft, in a news release Monday. Sunday was the last day underclassmen could declare themselves eligible for the draft.

Neither Coach Mark Turgeon nor Stoglin returned messages seeking comment.

Although the specific reasons for the suspension of both players were not immediately clear, the disciplinary action was precipitated by a violation of university policy rather than NCAA rules.

In the release, athletic director Kevin Anderson said: “Being a University of Maryland student-athlete carries a tremendous honor and responsibility. As much as we appreciate the effort these two young men gave to the program this season, they were unable to live up to that responsibility. We’re disappointed, but hope they use this as a learning experience.”

A 6-1, 185-pound guard from Tucson, Ariz., Stoglin, 20, was the first Terrapin since Joe Smith in 1995 to lead the ACC in scoring. He averaged 21.6 points per game for the Terps, who finished 17-15 (6-10 in the ACC) and missed the NCAA tournament, as well as the NIT, for a second consecutive year.

Stoglin had considered entering the NBA draft earlier this spring but changed his mind after Turgeon queried league officials on his behalf about his prospects.

After tweeting his decision to return to College Park for his junior season, Stoglin said in a telephone interview that he wanted to help lead Maryland to the NCAA tournament in 2012-13 and develop into a more complete player. Asked if there was any chance he’d change his mind, Stoglin emphatically said no.

On Monday, in response to tweets from Maryland fans wishing him well and lamenting his decision to leave, Stoglin tweeted: “wish I had the option bro.”

The year-long suspension of Stoglin and Parker represents the third black eye for Maryland basketball in less than four months.

Assistant coach Dalonte Hill was arrested in January for suspicion of driving under the influence and suspended two games.

Early Sunday morning, Pe’ShonHoward, the team’s presumptive starting point guard, was arrested and cited for disorderly conduct outside a College Park restaurant.

Stoglin’s departure leaves the Terps with a big scoring void to fill.

Turgeon has signed two promising shooting guards — 6-4 Sam Cassell Jr. of Baltimore and 6-1 Seth Allen of Fredericksburg — who should vie for the opportunity to do so, along with rising sophomore Nick Faust, a 6-6 shooting guard from Baltimore.

They join an impressive recruiting class that includes 6-9 center Shaquille Cleare of Houston; 6-8 forward Jake Layman and 6-8 power forward Charles Mitchell.

Stoglin’s zeal for taking over games was both a blessing and bane for Turgeon, who opened his first season in College Park with just seven scholarship players. Three recruits reneged on commitments after Gary Williams resigned as head coach, and Howard missed the first nine games with a broken foot, then missed the final nine with a torn knee ligament.

While Stoglin wasn’t always a reliable defender, he needed no coaxing when it came to offense. With experienced players in short supply, Stoglin instinctively took over the offense — sometimes playing within Turgeon’s system; other times, shooting without regard to it. He took more than twice as many shots last season as any other teammate and accounted for nearly one-third (31.4 percent) of the Terrapins’ points.

Stoglin single-handedly won numerous games. But his shoot-first instincts got him benched more than once — an approach that, at times, undermined the development of the players around him and tested the limits of Turgeon’s patience. He also irked Turgeon by tweeting his displeasure over being benched in the late stages of a 73-55 loss at Duke.

Not all NBA scouts view selfishness in a shooter as a bad thing. Allen Iverson, among Stoglin’s role models, became an 11-time NBA All- Star on a shoot-first approach. Similarly, some NBA teams may interpret Stoglin’s suspension from Maryland as a red flag; others may be willing to ignore it if they feel he can help their effort.
