(CBS) Bears safety Antrel Rolle has missed his team’s past two games after suffering a high ankle sprain in a Week 4 win against the Raiders, but he believes he’ll be ready this Sunday against the Vikings.

And he has a goal in mind: ending the Chicago secondary’s interception drought. The Bears’ defensive backs haven’t picked off a pass yet in the first six games of 2015.

“Let me tell you something: If I’m out there, I’m going to get me one,” Rolle said in an interview on the Spiegel and Goff Show on Tuesday. “Just know that. I’m going to find a way to get that ball this week. If I’m out there this week, I’m going to find a way to get the ball.”

The Bears have three interceptions this season, all from linebacker. Rolle believes the Bears secondary’s interception drought is the result of circumstance. That’s certainly the case on his behalf, he said.

“The crazy thing is … I went back and I watched all the games I took part in,” Rolle said. “Just for myself, selfishly speaking, I’m like, ‘Damn, I haven’t even had a chance to really get any interceptions.’ You know, there’s sometimes where you can think, ‘OK, if I would’ve done this, maybe got it.’ No, I just haven’t had the chance. Sometimes that’s just the way the ball drops.

Rolle is still rehabbing his sprained right ankle but expressed optimism he’d be back Sunday.

“I’m not sure exactly what’s going to take place, but that’s my plan,” Rolle said. “That’s been my goal ever since the injury took place. I’m still looking to obtain that goal and keep working until that day comes.

“The issue is I’m still rehabbing. You just have to take it day by day and see how I feel out there once I go full speed and let it progress itself. I’ve been attacking it extremely hard. I don’t think I could do anything more to it.”

Rolle also added he was unsure of the details surrounding the Bears’ release of starting defensive lineman Jeremiah Ratliff last week. Ratliff was let go after a heated confrontation last Wednesday with general manager Ryan Pace led to Lake Forest police being responding as a precautionary measure. The blow-up took place in front of Halas Hall as the team practiced.

It was just the latest in a series of issues with Ratliff, sources told 670 The Score.

For his part, Rolle was “sad” to see Ratliff go be didn’t know any more details.

“I haven’t been told anything,” Rolle said. “I’m not really sure what took place with Jay Ratliff. I found out through Twitter, I saw that Jay was released. I’m not sure what exactly took place. I wasn’t told to tell the media anything because I don’t even know what took place, to be honest with you.

“I’m extremely sad to not see Jay here. He’s a great guy. He’s  helluva competitor. Like I said, I don’t know what took place. I can’t really speak too much upon that.”
