They trailed slightly as RB Javarris James got a 1-yard TD run, followed by Mat McBriar's punt getting blocked and returned 2 yards for a touchdown by Taj Smith. They replied to get the lead back as QB Jon Kitna completed a 2-yard TD pass to TE Jason Witten (With a successful 2-point conversion as Kitna passed to WR Roy E. Williams), but the game was tied when James got a 2-yard TD run.
