Packers sign LT David Bakhtiari to contract extension

   MILWAUKEE (AP) -- Packers left tackle David Bakhtiari has signed a contract extension to stay in Green Bay, and a person familiar with the talks says it's a four-year deal worth up to $51.67 million.
   The person spoke to The Associated Press on condition of anonymity on Tuesday because details of the extension have not been announced. NFL.com first reported the extension for the lineman who protects quarterback Aaron Rodgers' blind side.
   General manager Ted Thompson announced the signing on Tuesday without releasing terms.
   Bakhtiari has been a starter up front since his rookie season after being drafted in the fourth round in 2013 out of Colorado.
   The signing comes less than two weeks after the Packers cut veteran left guard Josh Sitton , who signed with Chicago.
