Sterling was substituted in the 82nd minute as the Reds were pegged back after leading 2-1 in Bulgaria.
However, Liverpool boss Rodgers has suggested that the England international is likely to be fit for this weekend’s clash with Stoke City at Anfield.

“He was ready to come off and then he had the chance where he nearly scored.
“He was buckled over in pain for about six minutes and needed to come off.”
