John Sullivan agrees Charlton Athletic extension

John Sullivan
Sullivan's last three games have all resulted in clean sheets

Charlton Athletic have extended the loan spell of Millwall goalkeeper John Sullivan until the end of the season.

The 23-year-old joined the Addicks on 18 March but has made just one appearance, in their 0-0 draw with Oldham last weekend.

His chance after six games on the bench came following injuries to Rob Elliot and Ross Worner.

The former Brighton man, who had a loan spell at Yeovil earlier this season, is out of contract in the summer.
