The full list of tryouts for the Seahawks includes:
Callahan, 25, wound up signing a three-year, $1.62 million contract with the Packers as an undrafted free agent out of Wesley College back in May of last year. He was able to make the 53-man roster as the team’s No. 3 quarterback coming out of the preseason but was later cut loose.
Callahan had brief stints with the Saints and Browns before returning to the Packers during the 2016 season. Green Bay cut Callahan loose as they trimmed their roster down to 53 players and he was later signed to their practice squad.
The Packers re-signed Callahan as an exclusive rights free agent during the offseason, but he was let go and later signed by the Eagles. Unfortunately, Callahan was among their roster cuts coming out of the preseason.
In 2017, Callahan appeared in one game for the Packers and completed five of seven pass attempts for 11 yards and no touchdowns of interceptions.
Walford, 26, is a former third-round pick out of Miami by the Raiders in the 2015 NFL Draft. The Raiders elected to place him on waivers back in April and he was later claimed off of waivers by the Jets.
However, Walford lasted just a few months in New York, as he was unfortunately among their final roster cuts coming out of the preseason.
In 2017, Walford appeared in 13 games for the Raiders and recorded nine receptions for 80 yards receiving and no touchdown.
