Keith missed the last 15 minutes of the Hawks' win over the Toronto Maple Leafs on Saturday.
Keith blocked a shot with his right hand, briefly left and then watched the rest of the victory from the bench as a precaution and with the Hawks having a good lead.
Keith and defenseman Niklas Hjalmarsson, who has his own bumps and bruises to mend, didn't participate in practice on Monday at the BankAtlantic Center.
But "both are expected to play [Tuesday against the Florida Panthers]," coach Joel Quenneville said. "They should be fine."
Keith, who is paired with rookie Nick Leddy, has been playing like a Norris Trophy winner lately. He is a plus-6 with four assists during the Hawks' eight-game winning streak.
