The school district was also presented with an additional $1,000 worth of socks and underwear.
Metcalf was inspired to give back after a 2017 survey from JCPenney found that a third of American parents worry about their child having enough socks and underwear for the school year, with the percentage jumping to 40 percent for those in low-income households.
Metcalf was drafted by the Seahawks in the second round with the 64th overall pick in the 2019 NFL draft.
The 6-foot-4 inch, 230-pound former Ole Miss star stole the show at the NFL Combine in February when he ran a 4.33 40-yard dash – tied for the third fastest time at his position.
In the Seahawks first preseason game against the Broncos, Metcalf had one catch for 8 yards on four targets.
The Seahawks' next preseason game is Sunday against the Minnesota Vikings.
