Fiedler has sprained knee ligament

DAVIE, Fla. -- Miami quarterback Jay Fiedler has a sprained ligament in his left knee and underwent tests Monday to determine the extent of the injury.

Dolphins coach Dave Wannstedt said no update on Fiedler's condition would be made before Wednesday. Wannstedt also would not speculate how long Fiedler would be sidelined -- if at all -- because of the injury suffered in the fourth quarter of Sunday's 19-13 overtime loss to New England.

If Fiedler can't play, backup Brian Griese would start next Monday night at San Diego. Griese, signed in the offseason as a free agent, has not taken any game snaps since the postseason.

"When that player has something like this, it's not unusual for him to experience some swelling, soreness, stiffness, maybe even some looseness to his knee," Dolphins trainer Kevin O'Neill said. "Each player responds to it differently."

O'Neill said Fiedler had no "substantial" swelling in the knee when arriving for treatment Monday.

Fiedler was 2-of-5 for 48 yards in overtime, while wearing a brace to protect the knee. He also threw an interception on the Dolphins' final overtime drive, one of three turnovers Miami committed in the loss, which knocked them out of first place in the AFC East and ended a four-game winning streak.

Fiedler was not available Monday; players were given the day off. Fiedler's agent, Brian Levy, said he did not believe the injury was serious.

"I would know if it was," Levy said. "I think it's just a sprain."

Fiedler missed six starts last season with a broken right thumb; the Dolphins went 2-4 in those games, contributing to the team's slide from expected Super Bowl contender to non-qualifier for the playoffs. Fiedler also underwent arthroscopic surgery on his left hip before 2002's training camp, but did not miss any preseason games.

In some circles, Griese's signing was expected to create an all-out quarterback controversy with the Dolphins. But outside of one plane that circled Pro Player Stadium Sunday with a www.startbriangriese.com banner attached -- and sporadic boos directed Fiedler's way on game days -- no controversy has existed.

Fiedler's rating through six games, 71.8, is lower than his season rating for any of his three previous years as Miami's starter. And his inability to consistently connect on deep passes has made life easier for defenses geared to stopping running back Ricky Williams.

The only way to get people out of that is to hit a couple," Wannstedt said. "Until you hit them, people are just going to keep making us prove we can do it."

Griese signed a two-year deal with the Dolphins in June, after spending the previous four seasons as Denver's starter. He was slowed by a toe injury during preseason, but has been practicing again for three weeks, Wannstedt said.

But Wannstedt wouldn't speculate on how much of the offense would have to be changed if Fiedler's injury is serious.
