Mulumbu, Reid expected to play but Tamas a doubt for West Brom's Villa clash
Mulumbu picked up a knock on his knee in Sunday's Black Country derby win over Wolves whilst Reid had minor surgery on his hand after the game but should be fine for this weekend's short trip to Aston Villa.
However, Tamas missed the Wolves win because of a thigh problem and it is unsure if he will suit up against West Midlands derby foes Villa.
"Tamas is still injured," Hodgson told Albion's official website. "Mulumbu didn't train yesterday but it's not a serious thing for the weekend. He has a slight knee problem.
"Reid has had a minor procedure to do with this slight problem with his hand. He's had something inserted to stabilise it.
"He hasn't trained either - but he will be okay for the weekend."
