PLATTEVILLE, Wis. — Jim Miller is expected to miss two weeks with a strained left hamstring, hurting his chances of being the Chicago Bears' starting quarterback.
Miller had an MRI exam Saturday as a precautionary measure after being hurt in the second practice of training camp Friday.
"It's no worse today than yesterday, but we're looking at probably two weeks, give or take a day or two," Bears trainer Tim Bream said Saturday.
"We'll see how it is day-to-day. We probably won't know exactly the prognosis for another few days."
Miller tore his Achilles' tendon last November, had surgery and had spent long hours rehabbing during the offseason.
He'd hoped to battle Cade McNown and Shane Matthews for the starter's job during an open competition in camp.
"It is a setback," Bears coach Dick Jauron said Saturday, adding the Bears have no immediate plans to bring in another quarterback. "Jim worked so hard to get where he is. Clearly, when you're not on the field, you can't get a lot done. It just seems like the guy can never catch a break. Hopefully he'll heal more quickly than Tim thinks."
Miller has started just five games in his three previous years with the Bears. In his first start with Chicago, in November 1999, he passed for 400 yards against the Vikings. But he was suspended the final month of that season for violating the league's banned substance rules.
Last season he got another chance to start and led an upset of the Colts before tearing his Achilles' tendon the following week against Buffalo.
"It's unfortunate. I don't know anyone who's had worse luck than Jim the last couple of years," Matthews said.
Before camp began, Miller said he was just trying to look ahead and put all the tough times behind him.
"What do people call them? Character builders?" he said. "I don't need any more character. I know I've had enough of that."
While Miller was hobbling, top draft pick David Terrell was holding out. Terrell, the No. 8 pick overall, is the team's only unsigned draft choice.
Second-round pick Anthony Thomas, a running back and a teammate of Terrell's at Michigan, signed a four-year deal Thursday that reports say is worth $3.1 million.
Third-round choice Mike Gandy, a guard from Notre Dame, signed a three-year deal worth $1.42 million Thursday.
The Bears were obviously hoping Terrell's holdout would be a short one but were preparing for any situation.
"It's as much about the agent as it is the player," general manager Jerry Angelo said. "David has a playbook and has been talking with the coaches. He was in our spring camp and we don't feel he will be too far behind when he gets in here."
