The Manchester United loanee was set to miss today’s League One clash at Portsmouth after news of his shock suspension emerged yesterday morning.
Henderson was charged with improper conduct following an incident during Shrewsbury’s 3-1 defeat at promotion rivals Blackburn Rovers earlier this month.
Several objects are understood to have been launched toward the 20-year-old by home supporters at Ewood Park, after Charlie Mulgrew had scored a 70th-minute penalty for the hosts.
It was alleged the keeper then reacted by throwing an object which had landed nearby back into the stands.
Henderson denied the charge but it was upheld by an Independent Regulatory Commission, which studied video evidence before deciding to impose a three-game ban. The keeper was also fined £2,000.
Town yesterday confirmed via a brief statement, posted on Twitter, they were ‘aware’ of the charges but made no further comment. Boss Paul Hurst is expected to address the matter following today’s game at Fratton Park.
It is understood the club have requested a copy of the commission’s written reasons, which they are due to receive on Monday.
They will then decide whether there are grounds for launching an appeal.
Henderson, who joined on a season-long loan from Old Trafford last summer, has been a key figure in Town’s challenge near the top of League One, playing 25 of their 27 league fixtures prior to the ban.
In addition to the trip to Portsmouth, he is set to miss next Saturday’s game at Bristol Rovers and the home fixture against Plymouth on February 10.
Craig MacGillivray will replace him in goal. The 25-year-old former Walsall man has eight appearances to his name this season, though only two in the league.
