The speedy attacker missed last week‚Äôs 2-1 loss to Everton after injuring his foot when colliding with advertising boarding in the 4-3 West Midlands derby win over West Bromwich Albion the weekend prior.
Ahead of the home meeting with the Hammers, Lambert was looking forward to again having Agbonlahor‚Äôs pace in the front third.
"Gabby is looking good at the moment. We've missed him and his speed,‚ÄĚ he said.
"I think we should have got at least a draw against Everton. Having him back would be a major coup for us."
