Watford have confirmed that defender Sebastian Prodl has signed a new deal keeping him with the club until 2021.
The 30-year-old moved to Vicarage Road from Werder Bremen in 2015 following the Hornets' promotion to the Premier League and has since made 61 appearances in all competitions.
The Austria international - voted fans' player of the year for last season - still had three years remaining on his original deal but has bagged improved terms for committing to the club until 2021.
"I'm very blessed to sign a new deal here at Watford FC," Prodl told the club's website. "I hope to be back on the pitch soon and I'm looking forward to the next four years."
Prodl has been on the sidelines with a hamstring injury since the start of this month.
