Marrone said that Manuel has not suffered any injury setbacks in practice and he should be fine to start against the Pittsburgh Steelers on Sunday.
"He was not limping or anything," Marrone told the club's official website. "From the standpoint of being healthy, it is fine.
"Now it is just the point of trying to get him back and like I said, last week we did a good job of getting him out there and working."
Manuel was the 16th overall pick in the 2013 Draft.
