Greetings from NFC North blog headquarters, where I've returned for a 24-hour pit stop before continuing our Week 2 adventure. Remember, I'll be at Candlestick Park on Sunday night for the Detroit Lions' matchup with the San Francisco 49ers. While we have a moment, let's get inside a truncated Friday injury report that suggests the Lions will be without their two starting cornerbacks this weekend.
Detroit Lions: Cornerback Chris Houston (ankle) was a limited participant in practice for a third consecutive day, but was listed as doubtful on the injury report. I was assuming Houston would play in some role Sunday night after a two-week layoff, but that might not be the case. Fellow starter Bill Bentley (concussion) was ruled out, so the Lions might be left to rely on some combination of Jacob Lacey, Drayton Florence, Jonte Green and Kevin Barnes against the 49ers. If that's the case, all four of the Lions' starting defensive backs Sunday will be players who opened training either on another roster or as backups. Meanwhile, defensive tackle Corey Williams (knee) did not practice and is questionable, as is backup defensive end Lawrence Jackson.
