It's not going well for Johnny Jolly in Houston.  The 28 year old suspended Green Bay Packers defensive end will remain jailed without bond until his next court appearance on posession of codeine charges on April 20.  A judge denied bail when Jolly's attorney appeared for him at a court hearing in Harris County Wednesday.  Jolly was arrested early March 25 by police who during a routine traffic stop, found 600 grams of codeine in his car.  He was booked on a posession with intent to deliver charge, the same charges filed following an incident in 2008 when 200 miligrams of codeine was discovered in his car.  After one mistrial in that case, Jolly agreed to a deferred prosecution, avoiding jail time but was placed on probation and ordered to do community service.   The charges would be dismissed if he avoided more trouble in the probation period.  He hasn't.  Now, Harris County prosecutors can combine both cases.  The original charge carried a maximum 20 year prison term.  Jolly's attorney, Carl Moore, says his client will plead innocent.  The Packers have not commented on the case.  Jolly was suspended by the NFL for the entire 2010 season under the personal conduct policy and he was hoping to file for reinstatement this spring.  That may have to wait a while, possibly a very long while.
