Villa beat Norwich 1-0 in the Premier League at Carrow Road on Saturday but with a Capital One Cup tie ahead on Tuesday, Lambert admits he may have to field a patched up side against Tottenham.
Christian Benteke (hip), Gabby Agbonlahor (ankle) and Ashley Westwood (thigh) are all listed as doubts for the cup clash at Villa Park, while Fabian Delph and Antonio Luna are also suffering from knocks sustained at the weekend.
The quintet join an injury list already including Jorres Okore (knee), Charles N'Zogbia (Achilles) and Gary Gardner (back), leaving Villa with eight casualties ahead of the third-round clash and Lambert admits he could have to name players regardless of their fitness levels.
"I've never questioned their commitment to us, to the football club, to themselves and to their team-mates," he told the Birmingham Mail.
"Westwood hurt himself in training. He's just got a little strain. He's been brilliant for us. To lose him was a blow.
"There were a few knocks, but we had to get them out there. Luna just trained on Friday so he was touch and go. Obviously Okore's out, Gabby's hurt his ankle, Fabian's been struggling so the lads were running on empty."
Striker Benteke played a pivotal role last term but was forced to limp off limp away from proceedings early at the weekend but Lambert is hoping to have his leading man back when they host Manchester City on Saturday.
"It looks like his hip flexor at the moment," he added. "The good thing with Christian is he's usually a quick healer. I don't know how long, we'll have to just wait and see.
''I don't know how bad it is. Obviously we've got a game tomorrow but the most important one is the following one on Saturday."
