Redskins' Jansen breaks ankle in second quarter vs. Dolphins
"It was pretty serious," coach Joe Gibbs said. "We are just going to have to wait and see what the doctor says."
Jansen was hurt when he was sandwiched between defensive end Matt Roth and linebacker Zach Thomas, who rolled onto Jansen's legs while sacking Jason Campbell. Jansen immediately yanked off his helmet and grabbed his face in agony as his teammates quickly surrounded him.
"He was laying right there beside me hollering," Campbell said. "I knew it was something bad. I looked at his foot, and I turned and didn't look at it any more."
Jansen was carted off the field and managed to raise his right fist to salute the crowd as he entered the tunnel.
Stephon Heyer, a rookie free agent from Maryland, took Jansen's place for the rest of the game, which the Redskins won 16-13 in overtime. Heyer had subbed for left tackle Chris Samuels during preseason when Samuels was sidelined with a sprained knee.
"It takes away a little bit from the win," right guard Randy Thomas said. "I'm down about that. That's a blow, man. That's a rock."
Jansen, 31, is in his ninth season with the Redskins. Nicknamed "Rock," he was the team's most reliable player during his first five years in Washington -- never missing a start -- but his past three seasons have been filled with injuries. His missed the entire 2004 season with a ruptured Achilles tendon, broke both thumbs in 2005, and labored with a torn calf muscle for much of 2006.
He signed a five-year, $23 million contract extension earlier this year.
