Jamal Lewis' absence without explanation

We do not see the 31 browns jerseyat Wendesaday of Cleveland Browns' practice,and the team had no explanation for Jamal Lewis' absence.
Someone said he is going to retire after this season.The media have not see him in the Browns' locker room during the open session.There were no street clothes in Lewis' cubicle, and a Browns spokesman didn't give a reason for the running back not practicing.The spokesman said if Lewis doesn't practice, his status would be addressed on the week's first injury report, which will be released after 4 p.m. ET.
Has been bothered by injuries all season, Lewis might be placed on the injured reserve, which would bring an unhappy end to a brilliant 10-year NFL career.
