Bears releasing two-time Pro Bowler Tim Jennings

Cornerback Tim Jennings, who just 21 months ago signed a four-year extension with the Bears, is being released by the team Sunday.

The two-time Pro Bowler was the sixth cornerback used in Saturday night’s preseason loss to the Bengals. Coach John Fox gave a cryptic answer when questioned whether there was competition for the job.

“Everybody is,” coach John Fox said. “There’s 90 people — do the math.”

Jennings is guaranteed $4.4 million this season. He faced competition from Saturday starters Kyle Fuller and Alan Ball. Ball signed a one-year, $3 million deal this offseason. Sherrick McManis played nickel back, Terrance Mitchell has been a training camp star and Tracy Porter has been effective, when healthy.

Jennings said Saturday he was still gaining explosiveness back following February knee surgery.

“It’s making progress,” Jennings said. “From the [organized team activities], it was kind of slow. But coach is doing a great job easing my way back into it. I think every week it’s getting better. I’m moving a little bit better. We still have some progress that we still have to make, but as long as I feel like I’m getting better each week, that’s good.”

Then-GM Phil Emery signed Jennings to an extension in January 2014 after he made his second-straight Pro Bowl.

The Bears must trim their roster from 90 to 75 by Tuesday, and down to 53 Saturday.
