Bolder was taken ill during last week's 3-1 victory over Cheltenham Town as ruled unfit by physio Bobby Bacic having failed to shaken off the bug that knocked him for six during the first half of that game. However boss Kenny Jackett has recognised that The Lion need their most senior players fit and available in order to get their promotion ambitions back on track.
"Unless you've got a bundle of money you are never going to be able to bring in players who can adequately replace your best ones," he told the club's official website. "But we have still got enough quality here to win games, providing we can start to cut out the individual errors that have proved costly of late."
