"Nathan Tyson is not performing at this moment in time. He had two good chances in the opening minutes against Oxford and wasted both of them," said Gorman.
Wycombe loanee Drewe Broughton will serve out a ban after receiving his tenth yellow card of the season in the defeat at Oxford United on New Year's Day. The 26-year-old began a game for the first time under Gorman against Macclesfield Town on December 28, as the manager rotated his goal shy strikers amid the busy Christmas period.
The Southend United player was only a single caution away from a league suspension when he arrived at the club in December. Broughton will now miss the final two league fixtures at the end of the first half of his loan spell at the Causeway.
Even after Oxford had winger Chris Hackett sent off after 34 minutes, Wycombe still suffered a second 2-1 reverse in the space of five days.
