"Kurt trained this morning, which is positive, but we'll have to see how he is over the next 24 hours, while Mame hasn't been able to train because of a kick he received at the weekend," Lambert told reporters on Thursday.
Forward Eric Maxim Choupo-Moting (groin) and defender Kostas Stafylidis (rib) are also recovering from injury and are doubts for the visit of Mauricio Pochettino's fourth-placed side.
"Choupo-Moting is still missing and we have one or two other little issues too, but right now the biggest doubts are over Kurt and Mame...It's been a frustrating period," Lambert said.
Stoke are second from bottom with 27 points from 32 games and face an uphill task to ensure their survival.
The Staffordshire-based club, who have already yielded a league-high 61 goals this season, have lost to Tottenham by a four-goal margin in their last four meetings.
