Tobin, 28, wound up signing on with the Eagles as an undrafted free agent out of Iowa back in 2013. He managed to make the 53-man roster each of his first two seasons in the NFL before signing a two-year extension with the Eagles in 2016.
The Eagles later traded Tobin and a 2018 seventh-round pick to the Seahawks in return for a 2018 seventh-round pick.
Tobin signed a one-year contract with the Patriots this past March, but was released coming out of the preseason. He later had a brief stint with the 49ers.
In 2017, Tobin appeared in 15 games for the Seahawks.
