Team spokesman Patrick Smyth said Monday the Broncos hope Royal "will be ready for OTAs in late May."
Later Monday, Royal addressed the procedure on his Twitter account: "Thanks for all the support and prayers surgery was a success. I look forward to being back on the field and 100 (percent) come May"
A key component of Denver's deep receiving corps, Royal had a bounce-back season in 2010 despite dealing with a nagging groin injury all season.
The third-year pro caught 59 passes for 627 yards and three touchdowns. He also averaged 11.9 yards on 25 punt returns and 21.4 yards on five kickoff returns.
