Josh McCown has a shot to be the Miami Dolphins starting quarterback this season – but not if he keeps messing with chainsaws.

Josh and brother/fellow quarterback Luke McCown were cutting a tree stump two weeks ago when he cut the index finger of his throwing hand, according to CBSSports.com. The injury required six stitches.

McCown has promised the team he’s done with chainsaws at least for now. He’s got a two-year, $6.25 million contract to protect – and a chance to beat out Chad Henne and John Beck for a year or so.
