After dealing with a hamstring injury for more than a month in training camp, Hixon caught three passes for 44 yards in the preseason finale against Pittsburgh and seemed good to go for Week 1.
"I felt good,'' Hixon said Wednesday. "Yeah, I felt good.''
So why didn't he play?
"I wasn't told why, so I can't answer that for you,'' Hixon said. "I didn't ask. All I can do is practice throughout the week, show them I am ready to play and keep on working hard.''
Coach Ron Rivera indicated he held Hixon out to make sure the hamstring was fully healed, the same reason he gave for playing Armanti Edwards only one play.
Rivera said both will play 15 to 20 snaps Sunday at Buffalo, and that he likely will keep five wide receivers on the active list after keeping four against Seattle.
Rivera said Edwards in particular will be a bigger part of the game plan, which falls in line with his comment Monday that he'd like to open up the offense a bit more. Edwards is known more for his speed, while Hixon is more of a possession receiver at 6-foot-2 and 205 pounds.
