The Cowboys finalized a deal to make Mike Woicik their strength and conditioning coach.
Woicik replaces Joe Juraszek, who left the team because of a medical issue.
Woicik spent 11 seasons with the New England Patriots before his contract expired at the end of the 2010 season.
This is the second stint with the Cowboys for Woicik. He was the strength coach with the Cowboys from 1990 to '96 before leaving for New Orleans.
Woicik is the only player or coach with six Super Bowl rings. He won three each with Dallas and New England.
