Only once had Jordan Henderson left a Premier League match before the final whistle heading into Saturday’s game against Manchester City.
A heel injury in Liverpool’s 1-0 win made it twice, and Reds boss Jurgen Klopp is unsure how long he’ll be without his captain.

Henderson, 26, subbed out of the match for Divock Origi in the 65th minute, and he’ll not want to miss Monday’s match against his boyhood club, Sunderland.
“It’s a bit of a problem with the heel. I don’t know exactly what it is. I hope it’s not too serious.”
Henderson joined Sunderland at age 8 and stuck with the club through 2011. He’s been amongst the best defensive midfielders in the Premier League this season.
