Laurent Robinson didn't last long, and Tony Fiammetta wasn't away long.
The Cowboys had claimed Fiammetta after he was released by Carolina last weekend. He practiced with them Sept. 5 but was released two days later when Robinson, a receiver, was signed as insurance for Miles Austin. Austin had been nursing a hamstring injury, but he played in the season opener. Robinson injured his hamstring in his only practice on Sept. 7 and would have been unavailable anyway had Austin not been able to play. But, because Robinson is a vested veteran and was on the Week 1 roster, the Cowboys are obligated to pay his $685,000 salary.
Fiammetta retained his locker at Valley Ranch in the week he was off the roster. He was re-signed Tuesday, giving the Cowboys a fullback.
The Cowboys tried four fullbacks in training camp -- last year's starter Chris Gronkowski, draft pick Shaun Chapas, converted linebacker Isaiah Greenhouse and converted tight end Jason Pociask. They brought Greenhouse back on the practice squad for a week, but Greenhouse was waived Tuesday.
Tight end John Phillips played some fullback in the season opener against the Jets.
