Still working on conditioning

Bell estimated Thursday that his conditioning is back to "80 to 85 percent" following last season's torn ACL, Joe Schad of The Palm Beach Post reports.

Bell underwent surgery for a clean tear of his ACL last December and isn't on the injury report for Miami's Week 1 game against the Raiders on Sunday, but the rookie wideout is still working back into game shape. While he won't be on a proverbial pitch count against Las Vegas, there's a chance the Dolphins use multiple receivers with some sort of rotation. Bell is listed as a starter, but he's highly unlikely to run 100 percent of the routes Sunday. He could develop into the team's No. 1 wide receiver by the end of the season.
