This article is part of Football FanCast's Injury News series, which considers the impact of the latest updates on players' fitness.

Speaking to London News Online, Lee Bowyer confirmed that he will have three key players back fit for this weekend's game against Derby.

Ben Purrington, Tomer Hemed and Beram Kayal have all seemingly recovered from their respective issues, and Bowyer is expecting them to be back available.

The 42-year-old specifically spoke about Purrington's return, saying: "It’s really important that Ben is back because that left-back position is where we are short."

His return might be even more important, as Derby have a real danger-man lining up on Purrington's side...

Who is it?

Martyn Waghorn.

The Derby forward is the Rams' top scorer in the Championship this season with four goals to his name in ten starts, and has lined up on the right flank five times already this season - his last league start came on the right wing against Barnsley.

Waghorn is hardly the quickest player in the Championship, but what Purrington must be aware of is his knack of arriving in the box and taking up good goalscoring positions - the 23-year-old must be aware of the No.9's whereabouts at all times.

Significance of Purrington's return

Behind Purrington, Bowyer has just one other option at left-back in Lewis Page.

Unfortunately for Charlton and Page himself, the 23-year-old is yet to make an appearance this season as he struggles to stay fit.

When Purrington was out against Fulham, Bowyer opted for midfielder Jake Forster-Caskey at left wing-back, where he allowed Ivan Cavaleiro to cut in from the right flank and rifle home to find a second-half equaliser for the Cottagers - the ease with which the on-loan Wolves forward waltzed inside his man was concerning.

As a result, it is key for Charlton to have Purrington back fit and ready to perform, as Waghorn will certainly be a man to keep an eye on if his form so far this season is anything to go by.
