Leigh Griffiths and Craig Gordon are out of the Celtic side to face Hearts on Tuesday.
The Scotland striker scored the only goal of the 1-0 win over Hibs but went off injured after 28 minutes with a calf injury.
Gordon was replaced at half time by Dorus de Vries with his knee injury causing concern.
Speaking to Radio Scotland Brendan Rodgers said: “Craig took a nasty whack on his knee, we’ll just need to assess that but it’s not good news. I felt that Dorus came in and handled it well, he is experienced.
“Griff was frustrated, it was his calf, we’ll get the two of them scanned but it looks like they will miss Tuesday night’s game.”
Griffiths started the game with Odsonne Edouard on the bench and cashed in on hesitant defending to net from close range in the 27th minute.
Shortly afterwards he was beating the turf in frustration with a calf injury, Moussa Dembele took his place and now like starting on Tuesday against Hearts who drew 1-1 with Motherwell today.
