Oxford United manager Jim Smith has admitted insulting behaviour towards a match official for the incident when he offered a linesman his glasses.

United's manager took a dim view of the assistant referee's eyesight when he controversially flagged for offside against striker Marvin Robinson.

The incident, which caused great amusement, happened in the second half of United's 1-0 defeat by Kidderminster at the Kassam Stadium on March 21.

The ref ordered the U's boss to watch the remainder of the game from the stand.

Although Smith was subsequently charged with a breach of FA rule E3, which relates to "using abusive and/or insulting words towards a match official", and said he didn't remember saying anything abusive, he has admitted the charge in a letter, and declined the opportunity of a personal hearing.

"It will be dealt with as a non-personal hearing by an FA commission on Thursday (tomorrow) at the earliest," said an FA spokesman.

Sanctions open to the commission include a fine or a touchline ban, or Smith could simply be warned as to his future conduct.

Meanwhile, United's on-loan defender Mickey Corcoran was meeting with Cardiff City manager Dave Jones today to discuss his future.

The Northern Ireland Under 21 international joined Oxford in January on a 93-day emergency loan, which cannot be extended.

That means he is ineligible for the play-offs, unless Oxford are prepared to do a deal with Cardiff to sign him permanently.
