Favre's iron-man streak could come to an end

Here's a rundown of the significant injuries from Sunday's games:

Minnesota quarterback Brett Favre said his consecutive-game starting streak is in serious jeopardy  after re-injuring his surgically-repaired ankle against the Packers. In the unlikely scenario that he doesn't play in Week 8, Tarvaris Jackson would get the start.

San Francisco quarterback Alex Smith suffered a left shoulder strain against Carolina and had to leave the game. X-rays did not who any fracture and his status for next week is unknown.

Carolina  running back DeAngelo Williams has a foot injury that the coaching staff does not believe is serious. His status for Week 8 is not known.

Arizona quarterback Max Hall left Sunday's game with a head injury and was replaced by Derek Anderson. Hall has done little in his last two starts so look for Anderson to get the nod in Week 8.

St. Louis running back Steven Jackson had to leave the game against Tampa Bay with an undisclosed injury. His status for Week 8 is unknown. 

Indianapolis receiver Anthony Gonzalez recently aggravated his high ankle sprain and is one again out indefinitely.
