The Seahawks made it official this morning that TE Anthony McCoy is out for the season, placing him on the Injured Reserve list after he injured his Achilles tendon in practice on Tuesday.
It is the second straight year McCoy has injured his Achilles and been placed on IR.
To take his place on the 90-man roster, the Seahawks have signed free agent WR Ronald Johnson, who played for Carroll at USC.
Johnson was on the 49ers’ roster in 2011 and then with the Eagles in 2011 and 2012, but has not played in any games.
Johnson has not played since suffering what was deemed an “ugly” ankle injury with the Eagles in camp in 2012.
Johnson becomes the fifth USC player on the roster, and the second signed this week, joining cornerback Terrell Thomas.
Seattle now has what are listed as 15 receivers on its roster, though Morrell Presley is more rightly considered a tight end.
Still, Seattle has added two receivers with Los Angeles ties in the last week in Johnson and Randall Carroll, who played at UCLA.
Johnson had 138 receptions and 20 touchdowns in his USC career.
