The long-serving striker has missed the past three games since being forced off in the 70th-minute of last month’s 1-0 win at Tottenham Hotspur with a hamstring strain but is now back in full-training and gearing up for the Hammers clash.
His return gives Sherwood a selection dilemma, however, with the team putting in three impressive displays against Liverpool, Manchester City and Everton, respectively, in his absence, and the Villa boss stresses that he could have a fight on his hands to reclaim his spot.
"Gabby will get some game-time,” said Sherwood. “Whether it is from the start remains to be seen. But he will get game-time on Saturday. There are no other worries. We are as healthy as we have been.
"His return puts us in good stead for the remaining matches. The team is not picked yet. Everyone still has an opportunity.
"It's not only picked on what they have done in previous game, it's also picked on what they have done during the week. They are always on trial.
"Everyone gets judged on a level playing field and the boys who have the shirt at the moment are in possession.”
Meanwhile, the chances of seeing centre-backs Ciaran Clark and Nathan Baker back before the end of the season are growing ever-slimmer but Sherwood is pleased with the overall fitness of his squad, having seen both Alan Hutton and Scott Sinclair recover from their respective injuries.
“We are still struggling at centre-half with Ciaran and Nathan still missing but we seem to be getting bodies back,” added the Villa boss. "Obviously Alan got game-time in the last game. It's good to have him back. There's Scott too.
"These guys are all back in the squad now. We're looking healthier but as I said, in the centre of defence, there are only three.”
