Siliga, 25, wound up signing on with the 49ers as an undrafted free agent out of Utah back in 2011. He lasted just a few months with the 49ers before signing on with the Broncos and later being traded to the Seahawks for G John Moffitt. Seattle elected to waive Siliga a few months later before he signed to the Patriots’ practice squad.
The Patriots didn’t tender Siliga a restricted offer, making him a free agent.
In 2015, Siliga appeared in 13 games for the Patriots and recorded 28 tackes and no sacks.
