Bolton Wanderers loan Robert Hall, Danny Butterfield

Bolton Wanderers have strengthened their promotion bid by signing Robert Hall and Danny Butterfield on loan until the end of the season.

Winger Hall arrives at the Reebook Stadium from West Ham United, but he previously played in the Championship for Birmingham City earlier this season.

Butterfield, 33, has been brought in from Southampton, but he has not featured for the Saints since August.

Both players are expected to feature in Bolton's squad for their match with Charlton Athletic on Saturday.
