No surprises are anticipated when the NCAA’s early-signing period begins Wednesday, and all four Maryland men’s basketball oral commitments are expected to sign their national letters-of-intent within the week.

ESPN.com currently ranks Coach Mark Turgeon’s class of 2014 fifth overall nationally. The Terrapins were exploring the option of recruiting a fifth player to hedge against attrition, but have quieted down and appear content proceeding with this four-man class, by far the team’s highest-rated since Turgeon arrived in College Park. Maryland missed ESPN’s top 40 in 2013 and ranked 18th in 2012. Here’s where all four commits stand:

>> Shooting guard Dion Wiley, a four-star prospect ranked by ESPN as the nation’s 11th-best shooting guard, will sign during a ceremony at Potomac High School, beginning at 1 p.m. Post preps reporter Chelsea Janes will be there, so follow her on Twitter at CJanes15. Wiley, one of the nation’s most dangerous three-point shooters who played AAU with Team Takeover, committed in early June, choosing Maryland over offers from Florida, Miami, Georgetown and Indiana.

>> Four-star small forward Jared Nickens said via text message that he will sign his letter-of-intent at 2:30 p.m. from Westtown (Pa.) School. He committed less than two weeks after Wiley, saying at the time that he “just fell in love with Maryland.”

>> Bishop O’Connell point guard Melo Trimble, the first of the four to commit to Maryland in mid-December last year, will sign and fax his letter-of-intent during a school-wide signing ceremony on Friday, he confirmed via text to The Post’s Brandon Parker. A stocky four-star point guard ranked among the nation’s top 40 players by ESPN, Trimble might have even challenged for a starting job in College Park this season. As it stands, he will enroll with high expectations from a program that locked him down early.

>>According to his stepfather Daniel Moore, center Trayvon Reed will sign on Wednesday afternoon, whenever his family arrives at Life Center Academy in Burlington, N.J. This summer, Reed moved from his native Georgia to play for former Louisville star Pervis Ellison and to shore up his grades, which he has since done. His family plans to make the 12-hour drive to visit Reed, listed at 7 feet 1 and ranked by ESPN.com as the nation’s seventh-best center in his class, on signing day. “He’s ready to see what the future holds,” Moore said on Tuesday via phone.

None of Maryland’s three other commitments are expected to encounter any academic issues either.
