Bears linebacker Brian Urlacher didn't finish Sunday's overtime loss, gingerly walking off the field before the final play.
"Sore hammy. It's sore," Urlacher said on Fox Chicago. "Our trainers will look at it."
"I'll be able to walk out. It's not an injury," Urlacher said. "It's just sore right now. That's all it is."
Nick Roach, as he did in training camp, stepped in at middle linebacker with Urlacher out. On the final play, though, Seattle Seahawks rookie quarterback Russell Wilson completed a touchdown pass to receiver Sidney Rice.
The Bears defense allowed touchdown drives of 97 and 80 yards in the fourth quarter and overtime.
"We just didn't come through for our team," Urlacher said. "The zone read was killing us."
But Urlacher said the team had a good game plan, even though the defense looked ill-equipped to handle Wilson's read option plays.
"We just didn't make plays," Urlacher said. "We just didn't do enough to keep him in the pocket."
Urlacher was flagged for a second consecutive game for a horse collar tackle. Once again, the penalty was borderline, as he was tackling running back Leon Washington in the second quarter.
"They'll fine me, because that's what they do, and I'll appeal it," Urlacher said. "If it's even close, they throw the flag because they're really worried about payer safety on offense. It's very annoying to me. If it's close, they throw it.
"They don't give us [defenders] the benefit of the doubt."
