Boykin, 25, originally signed on with the Jaguars as undrafted free agent out of Virginia Tech back in 2012. He later caught on with the Packers after he was waived by Jacksonville a month after the signed him.
The Panthers wound up signing him to a one-year, $700,000 contract back in late March. However, he was among the team’s early roster cuts a few weeks ago.
In 2014, Boykin appeared in 13 games for Green Bay and caught three passes for 23 yards receiving and no touchdowns.
Pettis, 27, is a former 2011 third-round pick of the Rams. The Chargers wound up signing him to a contract in January to add depth at receiver. However, he too was among the team’s final roster cuts.
In 2014, Pettis appeared in five games and caught 12 passes for 118 yards receiving and one touchdown for the Rams.
