Sherwood revealed that Okore has played through the pain barrier in the final weeks of the season to help Villa win their survival fight.
Okore had missed virtually an entire season in 2013/14 when he ruptured his knee playing against Newcastle.
And he was feeling that very knee in the closing stages of this past term but elected to battle through for the good of the lions.
Sherwood referred to Okore as an "absolute warrior" adding that the aggressive and speedy defender was someone you'd "want in the trenches."
His involvement early on in the 2014/15 was extremely sporadic.
He was virtually fifth choice centre-half, behind Ron Vlaar, Philippe Senderos, Nathan Baker and Ciaran Clark - and had three unused sub appearances to his name as November came to a close.
But injuries to Vlaar, Senderos and Baker meant that Okore and Clark had to form a very youthful partnership at the back - and they performed heroically.
Okore referred to them as "partners in crime" as they excelled for the lions.
During their time together they earned impressive victories over Crystal Palace and Leicester City - as well as the vital double header over West Brom in the Barclays Premier League and the FA Cup.
With Clark rupturing his knee, Okore stayed in the team and partnered experienced Vlaar in the closing weeks of the term - and the pair also ensured vital wins over Everton and West Ham.
He missed the final-day Burnley match in the top-flight to rest his knee before returning for Villa's ultimately unsuccessful FA Cup final match with Arsenal.
He is now a vital member of Rémi Garde's set-up too.
Danish international Okore joined Villa in June 2013, with the claret and blues fighting off the likes of Chelsea to snap up the highly-rated stopper.
His first season was a nightmare as he missed most of the term but this campaign has been one of progress.
Now he'll be eager to kick on in 2015/16 - despite an operation in the summer to help his troublesome knee.
