Josh Sitton has said that he is optimistic of playing against the Washington Redskins later today.

The Green Bay Packers guard struggled with back pain against the San Francisco 49ers last Sunday and was unable to practise for the first half of this week.

The 27-year-old told the team's official website: "It hurts a pretty good bit of the time. Sometimes it locks up and spasms.

"It comes and goes, but it feels a lot better than it did a few days ago. If I feel like I can play, I'll play."

Head coach Mike McCarthy added: "I thought Josh looked good today. Hopefully, he comes in here tomorrow and has progressed the way he has the last couple of days."

Sitton started every regular season game for the Packers last season.
