The Buffalo Bills brought in free agent P Matt Darr for a workout on Monday, according to his agent Brett Tessler.
Barr worked out for the Jaguars last week but left Jacksonville without a deal.
Darr, 25, wound up signing on with the Dolphins as an undrafted free agent out of Tennessee back in 2015. He was in the final year of his three-year, $1.576 million contract and set to make a base salary of $615,000 for the 2017 season when the Dolphins elected to cut him loose coming out of the preseason.
