Lawrence Tynes, the kicker who has helped the Giants win two Super Bowls, is an unrestricted free agent. So the Giants may be preparing for life without Tynes by adding Buehler and Jake Rogers, a free agent signed earlier this offseason to a reserve/future contract.
Buehler, 26, was with the Dallas Cowboys from 2009 to '11. He handled kickoffs and made 24 of 32 field goal attempts and 42 of 44 extra-point attempts in 2010.
In 2011, Buehler played in four games handling kickoffs before landing on injured reserve with a torn adductor muscle that required surgery. He did not play in 2012.
Tynes converted 33 of 39 field goals in 2012, his sixth season with the Giants. He sent the Giants to the Super Bowl by nailing the winning field goal in overtime of the NFC Championship Games during the 2007 and '11 seasons.
