Howard Balzer reports that the Bills brought in four players for tryouts on Monday including P Matt Darr, P Taylor Symmank, P Matt Wile and LS Derek Hart.
Darr 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.
In 2016, Darr appeared in all 16 games for the Dolphins and totaled 3,691 yards on 90 attempts (41.01 YPA) to go along with five touchbacks.
