The 22-year-old came on as a 64th minute substitute at Cardiff City last Saturday, less than five months after signing a two-year development contract at the Madejski Stadium in July for Royals manager Steve Clarke.
Liburd, pictured in action during his side's 2-0 reverse in Wales, scored 22 goals for the Blues in the Ryman's top flight last season. Just 11 months ago, he was turning out for Thamesmead Town after breaking his arm and being loaned out by the Essex club during his recovery.
Rejected by Chelsea's academy aged 10, Liburd spent four years on a scholarship at Thomas University in Georgia, USA, winning a national college award before returning home to Croydon.
Having failed to win a contract at then League Two Southend United in the summer of 2014, he made his Championship debut in front of more than 15,000 supporters.
Congratulating Liburd, a Blues spokesman said: "He joked that it was the quickest 30 minutes of his life. Well done Rowan, we are all very proud."
After making his debut, Liburd told the Southend Echo this week: “I have been in the match day squad three times but haven’t made it on so I was delighted when I got the call against Cardiff.
"I am just keeping my feet on the ground keeping humble and I hope I can push on.”
