The 27-year-old tight end fills the roster spot vacated when Seattle released Kellen Winslow earlier Saturday. Moore caught four touchdown passes for the Cleveland Browns last season. The Browns released him.
Seattle had been expected to utilize Winslow and Zach Miller in tandem this season. Carroll, entering his third season as the Seahawks' head coach, had sounded excited about the possibilities.
The 75 receptions Winslow made with Tampa Bay last season exceed by 13 the three-year career total for Moore. Moore set a career high with 34 receptions last season while playing 31 percent of the offensive snaps. Winslow played 80 percent, but the Seahawks apparently weren't willing to pay his $3 million salary for a player with knee problems.
Moore stands 6-foot-6. He ran a 4.74-second time in the 40-yard dash at the 2008 NFL scouting combine, weighing 233 pounds. Moore is now listed at 250.
"Moore creates mismatches in the passing game with his length, especially in the red zone," Scouts Inc. said as part of its report on him.
Note: Moore began his career with Green Bay in 2008. Seahawks general manager John Schneider was with the Packers at that time.
