Lions defensive end Israel Idonije said he'll have some extra motivation for Sunday's game against the Bears but it has nothing to do with playing his former team.

In the Lions win over the Redskins last week Idonije didn't record a single tackle and his only statistical contribution was one quarterback hurry.

"It's extremely motivating" Idonije said of his lack of production in Week 3. "After watching this last game on Monday I went back and I watched the first two games -- not good enough.

"There's one focus and that's improving production. Everything else to the wayside."

Through three games Idonije has just three tackles and that quarterback hurry and he called his performance "subpar." With defensive end Jason Jones (knee) on injured reserve the Lions need Idonije to step up quickly along with fellow ends Willie Young and rookies Ziggy Ansah and Devin Taylor.

The Lions signed Idonije to a one-year contract this offseason after the Bears chose not to re-sign him. He played nine seasons in Chicago.

"I have no problems with blocking out stuff" he said. "(I'm) just focusing on ultimately number one being physically ready to play at a high level and then number two executing when I get into the game and being able to make plays that I've made in this league for a long time."

Idonije has 28.5 career sacks and 20.5 of those came the last three seasons.
