Toon, 26, was entering the final year of his four-year, $2.51 million rookie contract when he was released by the Saints as they reduced their roster a few week ago.
This is the first reported interest in Toon since he became available.
In 2014, Toon appeared in seven games and caught 17 passes for 215 yards receiving and a touchdown for the Saints.
Dez Bryant is expected to miss around six to eight weeks after he sustained a broken bone in his foot during Week 1’s game, so it’s not surprising to see Dallas bring in some veteran options this week.
Nicks, 27, signed a one-year contract with $100,000 guaranteed with the Titans back in April. However, he was among the team’s final roster cuts this past weekend as they got down to 53 players.
In 2014, Nicks appeared in all 16 games while with the Colts, but could only reel in 38 receptions for 405 yards and four touchdowns. Pro Football Focus has him rated as the No. 105 receiver out of 110 qualifying players.
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.
