CLEVELAND (AP) --Browns running back Jamal Lewis and kicker Phil Dawson missed their second straight day of practice.

Lewis (hamstring) and Dawson (knee) missed last Sunday's game in Baltimore and may have to sit out this week against the Cincinnati Bengals. Lewis did not participate in Thursday's team workout, but he rode a stationary bike and did some stretching and running drills with one of the team's trainers. Dawson was not seen on the field.

Browns coach Eric Mangini said it will be the end of the week before he knows if Lewis or Dawson can play.

Kicker Billy Cundiff was signed one day before the Ravens game last week and booted a 29-yard field goal.

Offensive lineman Floyd Womack (ankle) and defensive end Corey Williams (knee) also missed practice.
