The Cowboys couldn't work out a long-term deal with Tony Fiammetta, so instead they replaced him with veteran Lawrence Vickers.
Vickers was released by the Texans earlier this week after helping Adrian Foster rush for 1,224 yards and 10 touchdowns last season. It was the fourth time in six seasons that Vickers has had a 1,000-yard rusher behind him. Jamal Lewis rushed for 1,000 yards in both 2007 and '08 while Vickers was blocking for him in Cleveland, and Peyton Hillis had 1,177 in 2010.
Vickers has only 34 carries for 87 yards and no touchdowns in his six seasons, though he has caught 45 passes for 300 yards and three touchdowns.
