28-Year-Old Defender West Ham United Premier

O'Brien is dealing with a minor knee injury that is leaving his status for Saturday's match against Crystal Palace up in the air, the Daily Star reports.
O'Brien dealt with a dislocated shoulder last season and his injury woes have continued into 2014-15. While his knee injury isn't as serious as the shoulder injury last year, the 28-year-old should be a late fitness test against Crystal Palace.
