Celtic are waiting on scan results to determine the extent of Callum McGregor's calf injury.

The midfielder missed his first match of the season through injury as the Hoops beat Motherwell 4-1 on Sunday to restore their eight point advantage at the top of the SPFL table.

With Scott Brown suspended it meant a brand new midfield, with Nir Bitton returning to the side alongside Ewan Henderson who was starting his first ever top team match.

"He's picked up an injury from the midweek," Rodgers said, as quoted by The Daily Record, when explaining McGregor's injury.

"We would've taken him off but we were down to 10 men and he didn't feel it too bad. But then the last few days its stiffened up so we'll see what the result of the X-ray is on that."

Rodgers will be hoping to have McGregor available to face Hearts on Wednesday but surely won't take any chances with a Scottish Cup quarter-final against Hibs following three days later.

McGregor has been a crucial member of Rodgers' plans this season - his appearance against Valencia was his 54th match for club and country this season.

With Ryan Christie picking up a hamstring knock in the win over Motherwell, Bitton or Henderson could retain their place in the side to face Hearts if McGregor fails to prove his fitness.
