EAST RUTHERFORD, N.J. – The Giants today added their leading kickoff returner to the roster in advance of their home game tomorrow against the Atlanta Falcons.

C.J. Board, who was elevated to the roster before each of the first two games, was formally signed off the Giants' practice squad. The Giants also activated veteran center Jonotthan Harrison, who was signed to the practice squad earlier in the week.

In a corresponding move, linebacker Cam Brown was placed on injured reserve with a hamstring injury.

Board played six snaps on offense against both Denver and the Washington Football Team and 10 on special teams vs. the Broncos and 18 in Washington. He has all three of the Giants' kickoff returns this young season and is averaging 26.7 yards with a long runback of 38 yards. Board also has one six-yard catch.

In his first season with the Giants in 2020, Board played in 14 games with four starts and caught 11 passes for 101 yards, with a long reception of 16 yards, and had one rushing attempt for three yards. Board also returned two kickoffs for 54 yards and one punt for six yards.

Harrison, 6-4 and 300 pounds, was released in the cutdown to 53 players on Aug. 31. He had been with the team since Feb. 24. Harrison played in the Giants' final two preseason games, including a start at center in Cleveland on Aug. 22. He has played in 84 regular-season games with 42 starts for Indianapolis and the Jets and played in one postseason game for the Colts. Harrison has made 40 starts at center, one at left guard and one at running back.

Brown, a second-year pro, injured his hamstring in the season opener vs. Denver. He was inactive against Washington. Because he was placed on I.R., Brown must miss at least an additional three games.

As a rookie in 2020, Brown played in 15 games, most frequently on special teams. He recorded seven tackles (five solo) and three quarterback hits on defense, plus six tackles (three solo) and one forced fumble on special teams.
