Even though Indianapolis Colts coach Chuck Pagano has suggested wide receiver Austin Collie would probably play in the opener, Collie himself is unsure, NFL.com reported. Collie has been bothered by concussion-related problems after sustaining his fourth concussion in two years during the preseason. He said he can't tell yet whether he'll be able to play against the Bears. "We're just going to continue to see how I feel," said Collie, according to NFL.com. "I don't want to make a definite statement of 'Yes, I am playing on Sunday'; 'No, I'm not playing on Sunday,' because we still have time. I want to see how things go today. I want to see how things go tomorrow, and we'll go from there. "Whatever the doctors say, whatever the coaches say, I'm going to obey. I'm not focused about Sunday or what's going to happen. What I'm focused on now is just getting better today." Collie has been practicing with the Colts but requires medical clearance to play on Sunday.
