BEREA, Ohio (AP) -- Trent Richardson's pro debut, delayed by an unexpected surgery, appears to be on schedule.

The Browns rookie running back practiced again Wednesday for the second time since having knee surgery on Aug. 9. The No. 3 overall pick in April's draft, Richardson is expected to play and perhaps even start Sunday when Cleveland opens the season at home against the Philadelphia Eagles.

Richardson missed the entire preseason, but the Browns believe the former Alabama star is prepared to play despite a lack of contact.

Eagles coach Andy Reid said the 5-foot-9, 230-pound Richardson is "built for the NFL with speed, toughness, quickness, and you better wrap him up and make sure that you tackle well with him."

Browns coach Pat Shurmur said if Richardson is able to play this week he will start.
