Terrance Williams scored the go-ahead touchdown late in the fourth quarter, and Bruce Carter returned an interception 25 yards for a TD on the next snap, as the Dallas Cowboys beat the Rams 34-31.
The Rams jumped out to a 21-0 lead including a pick six of their own off Tony Romo, when Janoris Jenkins stepped in front of a pass and cruised 25 yards to put the Rams up three scores.
Austin Davis went 30 for 42 for 327 yards with three touchdown passes including two in the first quarter. A one-yarder to Lance Kendricks on the opening drive and then a 51 yard pass on the first play of the second quarter to Brian Quick.
The Rams have a bye week, then Shaun Hill will be back as starting quarterback.
This loss tied the second-largest lead blown ever by the Rams who fall to 1-2.
