Baltimore Ravens tight end Dennis Pitta underwent surgery Saturday night and will miss the entire 2013 season after dislocating his hip in practice Saturday, a league source told ESPN NFL Insider Adam Schefter.
"Dennis has a dislocated hip. We'll have to take a look at that and see exactly what it is," Ravens coach John Harbaugh said after practice. "It's a serious injury. He is going to be out for a while. He will not be in the Denver game and we'll just have to play it from there to see how long it goes."
A Ravens official confirmed Sunday that Pitta underwent surgery on Saturday night.
The Super Bowl champions begin defense of their title on the road against the Broncos on Sept. 5.
Pitta was preparing for his fourth season with Baltimore and was entering the final year of his contract. The 6-foot-4, 245-pounder caught 61 passes for 669 yards and seven touchdowns last season.
In the playoffs, Pitta had 14 catches for 163 yards and three scores.
With Pitta gone, the Ravens are without two of their most productive receivers last year. Pitta's 61 catches were tied for second with Ray Rice behind Anquan Boldin, who was traded to San Francisco during the offseason.
"Obviously, he was a very, very productive guy for us," Ravens offensive coordinator Jim Caldwell said of Pitta. "He made a lot of big plays last year. We'll see what happens. But somebody is going to have to step up. We do have some capable guys all across the flanks. We do have some weapons. We're just going to have to have some guys make some plays for us."
With the Ravens looking for a replacement, an NFL source told ESPN that one option is former Vikings tight end Visanthe Shiancoe.
"The ball is in his court right now. It's his decision to make," the source said.
The Ravens were reportedly considering signing Shiancoe even before the injury to Pitta. Shiancoe played in just four games last season with the Patriots, and did not have any catches.
In his first three NFL seasons, Pitta has 102 receptions for 1,075 yards and 10 touchdowns over 43 regular-season games.
