Update: Smith (concussion) is questionable for Sunday's game against the Giants and is expected to play, the Baltimore Sun reports.
Recommendation: With championships on the line, you'll probably want to check back on Sunday before locking Smith into your lineup. Unfortunately, that could pose a problem for some fantasy owners since the Ravens kickoff at 4:25 ET. As far as risks go, Smith sitting Sunday seems to be a relatively small one, but you'll probably want to have a Plan B in place anyway. There are only two other late afternoon games on Sunday, Cleveland-Denver and Chicago-Arizona, plus a Sunday night matchup between the 49ers and Seahawks.
