Wistrom fractures left knee

KIRKLAND, Wash. -- Seattle Seahawks defensive end Grant Wistrom will be out 4-to-6 weeks with a small fracture in his left knee.

After Seattle's 30-20 loss to the defending Super Bowl champion
Patriots on Sunday, dropping the Seahawks' record to 3-2 after a
3-0 start, the team got the bad news about Wistrom. Seahawks'
doctors initially believed Wistrom had only hyper-extended his left

"It was a little bit more than I heard right after the game,"
coach Mike Holmgren said. "He has a little crack. The slight
fracture has to heal first of all."

Wistrom, who spent his first six NFL seasons with the St. Louis
Rams, signed with the Seahawks in the offseason, getting a $33
million, six-year contract that included a $14 million signing

Holmgren also said Monday that wide receiver Bobby Engram
sprained his left ankle and may miss next week's game at Arizona.

The loss of Wistrom is a major blow to Seattle's defense, which
is allowing only 15.2 points per game and is already missing
starting linebacker Chad Brown, who broke his left leg in training

"It's a hit," Holmgren said. "There's no question about it.
He (Wistrom) was our No. 1 acquisition in the offseason. He brings
a lot of energy and started the season well for us."

Wistrom will most likely miss Seattle's visit to St. Louis on
Nov. 14.

"This really comes at a bad time," he said. "I really need to
get on the field and help these guys."
