Brendan Rodgers' side will face Southampton in an FA Cup semi-final at Wembley on the weekend of April 17/18, but that will likely come just too soon for the winger.
The England international suffered a knee injury during a home defeat to Arsenal at the end of February and required surgery following damage to his patella tendon. Post-match, Rodgers revealed the player was expected to be ruled out for six weeks, but he is yet to return to outdoor training.
The Daily Mail now report that the Foxes are hopeful that he will make a comeback at the end of April or start of May.
Barnes has enjoyed a successful season so far, scoring 13 goals and providing four assists in 35 appearances. He's undoubtedly been one of Leicester's most consistent performers this campaign and he'll be desperate to return and play his part.
Leicester currently sit third in the Premier League and will be hoping to qualify for next season's Champions League after just falling short last year. West Ham in fifth are seven points adrift of the Foxes and although there is still plenty of football to be played, a place in Europe's premier competition is very much Leicester's to thrown away.
A semi-final appearance in the FA Cup presents this group of players with an opportunity to go on and make history given the club have never won the competition before.
However, it is crucial Barnes isn't rushed back. He is on Gareth Southgate's radar and would have likely been included in the England squad to face San Marino, Albania and Poland had he been fit, while a place in their Euro 2020 squad is still up for grabs.
