Watt, 25, was taken in the third round of the 2014 NFL Draft by the Chargers. He was in the third year of his four-year, $2,816,640 rookie contract and was set to make a base salary of $600,000 this season before being waived with a failed physical designation.
The Chargers placed Watt on the PUP list to open training camp and kept him on the list at the start of the regular season but was unfortunately waived last month.
In 2015, Watt appeared in five games and played a total of 184 snaps for the Chargers.
Stewart, 23, wound up going undrafted out of Ohio Dominican back in May but later signed on with the Buccaneers before being waived with an injury designation a few weeks later.
After clearing waivers, he reverted to the Buccaneers’ injured reserve but was cut loose back in June. He had a brief stint with the Redskins and later signed on to the Packers’ practice squad a few months ago.
During his four-year college career, Stewart totaled 196 receptions for 3,197 yards receiving (16.3 YPR) and 25 touchdowns. He also contributed 416 kick return yards and 171 punt return yards to go along with one return touchdown.
