In the Rams' third offensive game, 

Dallas' Dolance Armstrong broke 

the offensive line 

and attacked Matthew Stafford.

Lawrence returned a fumbling 19 yards on 

the Rams' opening run for a touchdown as 

the Cooper Rush won Sunday 22-10. 

Despite passing just 102 yards against Los Angeles, 

he remained undefeated as 

the Cowboys' fill-in starter.
