Bears quarterback Jay Cutler underwent tests Monday that indicated he suffered a strained hamstring in Sunday's loss to the Cardinals, coach John Fox told reporters.
"Any time it's not real severe, I think it's good news," Fox said during his Monday press conference. "We'll just evaluate it going forward. We have game-planning tonight for Seattle and tomorrow and players are back in on Wednesday."
Cutler was injured late in the second quarter while chasing Arizona safety Tony Jefferson on a 26-yard interception return touchdown. Before the pick, Cutler had completed 8 of 8 passes for 120 yards and led the Bears in rushing with 24 yards.
Fox did not provide a timetable for Cutler's return. Asked if Cutler could practice Wednesday, Fox said: "Is it going to be heads or tails on Sunday? I don't know."
More information will be known Wednesday when the Bears are required to release their first injury report of the week in advance of Sunday's game in Seattle.
After replacing Cutler against the Cardinals, backup Jimmy Clausen completed 14 of 23 passes for 121 yards with one interception and a 56.6 passer rating. While Cutler helped generate touchdowns on two of three possessions, the Bears did not get into the end zone on nine drives after he exited.
Fox acknowledged that Clausen was put in a difficult situation against the Cardinals, coming in cold off the bench without much preparation time during the week.
"As I mentioned [Sunday], for the circumstances and his preparation reps and getting ready to play Arizona, most backups are not getting all those reps regardless of the position," Fox said. "I think at the quarterback position it's a little tougher because you have to be in tune to everybody else completely. But I think all-in-all he did OK."
Asked if Clausen will start Sunday in Seattle, Fox said: "It's yet to be determined."
Fox also indicated that the Bears have not yet decided whether to sign another quarterback. Second-year pro David Fales is currently on the practice squad.
"We'll evaluate that and we have all the way until Saturday to do anything like that," Fox said.
