Collie himself isn't so sure.
Calling his concussion-related issues "frustrating" and referring to his status as a "day-to-day thing," Collie made no promises he'll be available when the Colts open up their season against the Chicago Bears on Sunday.
"We're just going to continue to see how I feel," said Collie, who suffered his fourth concussion in two years during the preseason. "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."
Collie has been practicing with the Colts but will need medical clearance to play on Sunday.
"Whatever the doctors say, whatever the coaches say, I'm going to obey," he said. "I'm not focused about Sunday or what's going to happen. What I'm focused on now is just getting better today."
