Henderson has missed the last three months with a groin injury suffered in the Merseyside derby in February, having undergone surgery to repair the damage.
The midfielder was initially expected to return before the end of the campaign, but despite having now reported back to training at Kirkby, he will not feature against Crystal Palace on Sunday.
Instead, his focus will be on securing a spot in Gareth Southgate’s England squad at this summer’s Euros.
After the session, Henderson took to Twitter to express his delight at making a comeback, saying “it’s been a good day”:

Southgate is due to give Henderson every chance of proving his fitness ahead of the tournament, which takes place across Europe, and it is likely he will be involved.
But his presence in training ahead of Liverpool‘s final-day clash with Palace is a major boost regardless, with the captain able to help his squad in the buildup to a must-win game.
It was clearly a lift for Andy Robertson, who hailed Henderson on his return:
