Fill-in Costa may have earned job on Cowboys' line

When center Andre Gurode reported to
Dallas Cowboys training camp with a recently repaired knee, Phil
Costa was bumped up to the first team.
Gurode returned to play Saturday and immediately regained his
spot over the ball in front of Tony Romo. However, Costa may not be
going far.
Team owner Jerry Jones practically promised Costa a spot in the
starting lineup, either in Gurode's place at center or perhaps at
left guard, where rookie David Arkin is playing.
Jones says he' doesn't know "if anyone has had a better
preseason than he's had."
On Saturday, Arkin was still at left guard on the first team,
with Costa snapping for the second team.
