Oxford United manager Chris Wilder said:
"We are very mindful of the past and the situation. Luke is very contrite and sorry about what happened.
"He was sentenced and went to prison and during that time had the opportunity to reflect on what he had done.
"It is hard to separate the two, but purely from a football perspective he is an experienced goalkeeper who has played most of his games in League One and the Championship.
"We have a situation here where our number one goalkeeper is out for the foreseeable future with a shoulder injury and we could lose Max Crocombe to International duty next month.
"We are offering Luke a chance to play again.
"I have spoken to Luke at length and he knows that it will not be easy for him but he is very humble and wants to try and make the most of the opportunity."
