Jets S Rontez Miles and OL Jonotthan Harrison will likely be out this week, coach Todd Bowles said on Thursday.
Miles will miss his second straight game with two orbital fractures, while Harrison suffered a concussion during the team's practice on Wednesday.
Bowles is not certain what caused Harrison's concussion, but believes he had contact with another player. "I guess it happened in individual period," Bowles said. "Maybe it hit him the wrong way or his helmet, I don't know. It just happened. I just found out."
Miles played in all 16 of the team's games last season, tallying 31 tackles and starting four games. Harrison signed with the Jets this off-season after spending last season with the Indianapolis Colts. He played in 44 of games and had 23 starts for the Colts.
