The Chicago Bears thought their kicking problems had finally ended when Eddy Pineiro made a 53-yard field goal to beat Denver last week.

No such luck.

Pineiro will go into Monday night's game in Washington questionable on the injury report because of right knee trouble.

Pineiro was hurt Friday, with coach Matt Nagy saying it happened during weight training. Pineiro didn't practice Friday but did kick on a limited basis at Saturday's practice.

The Bears conducted an offseason kicking search after Cody Parkey double-doinked a 43-yard field goal at the end of a 16-15 playoff loss to Philadelphia last season. Pineiro is 4-for-4 on field goals this season.

"Especially after what just happened with us and what we've been through [with kickers], and what he just did this past weekend, it's like we're on a roll here and then all of a sudden something crazy like this happens," Nagy said. "But I try to stay positive with it and I think we'll be OK. We've just got to see how it goes the next couple days."

Punter Pat O'Donnel is a possible fallback on Monday, Nagy said.
