The 29-year-old has fallen down the pecking order at The Hawthorns this season and has started just one game since Tony Mowbray took charge of the side last month. Mowbray has now decided it would be in Wallwork's best interests to get some games under his belt elsewhere. He is expected to complete a switch to Oakwell within the next couple of days, and remain there until January 1. West Brom will have the right to recall the former Manchester United man after 28 days and he will not be eligible to play when the two sides meet next month.
