Janikowski spent 17 seasons with the Oakland Raiders but missed the 2017 season due to a back injury. Janikowski, 40, has made 80.4 percent of his kicks during his career and holds the NFL record with 55 field goals of 50 yards or longer.
Janikowski will join former Jacksonville kicker Jason Myers in the competition to replace Blair Walsh, who was inconsistent in his one season as the Seahawks kicker last year.
Morris spent time with three teams during the regular season and was with Washington earlier this offseason before being released this month. Seattle had no other quarterbacks on the roster since Trevone Boykin was released late last month.
McKissic developed into Seattle’s third-down running back for part of last season. McKissic appeared in 13 games and had three touchdowns. He averaged 4.1 yards per carry in limited work as a ball carrier, but was most effective as a pass catcher. McKissic had 34 catches, fifth-best on the team.
