KANSAS CITY, Mo. -- Buffalo Bills coach Rex Ryan questioned the number of replays of controversial calls being shown at Arrowhead Stadium during Sunday's 30-22 loss to the Kansas City Chiefs.

"That's the first time you don't see any plays," Ryan said after the game. "I think there's a league rule that you need to usually get to see some. Maybe I'm wrong on that."

Ryan elected not to challenge a 37-yard reception by Jeremy Maclin in the second quarter in which the Chiefs receiver appeared to trap the ball against the ground. The Chiefs scored a touchdown on their next play.

"The 37-yarder, I wasn't aware of it because again, I wasn't seeing the video on it, and again, so from my vantage point, I thought he caught the ball," Ryan said. "That was from my vantage point. Obviously, I would have challenged it if I would have known there was any question whatsoever on a 37-yard play that flipped the game. We were in complete control of that game, and then they threw some balls over our heads. Obviously I would have challenged [that]."

Ryan did not identify which members of his staff were advising him on replays from the coaches' booth but told reporters that they did not have access to replays on close plays.

"A lot of times everybody will be up there, but I'm not saying anybody in particular is advising me because it never worked out," he said. "Every decision is my decision, and so it's my responsibility.

"It's not [like] where this guy has that job to do it, or whatever. There's other jobs in there. And if you don't show the replay, then he can't see it, either. So it doesn't matter. If you can't see a replay, then how is anybody up there going to know to challenge or not?"

An incompletion to Buffalo's Robert Woods in the third quarter prompted Ryan to use his first challenge, but it was unsuccessful, leading Ryan to be more leery about using his red flag through the remainder of the game.

Ryan did not challenge a questionable spot on a run by Kansas City's Alex Smith for a first down on the final play of the third quarter nor an incompletion to Buffalo receiver Chris Hogan that appeared to be a catch late in the fourth quarter.

"The Hogan one was a bang-bang play," Ryan said. "I never thought it was gonna be reversed. I thought he caught it, but it's too close to call whether he had it or not, so I was like, I wasn't gonna do it then."

Ryan used his second and final challenge two plays later on a fourth-down scramble by Tyrod Taylor that ended short of a first down; he was again unsuccessful.

"At the end of the game, that's my decision, 100 percent to challenge it, for the simple fact that I thought it was game on the line, I knew it was close -- it was close whether Tyrod was in or out," he said. "It looked like he was in bounds. I wasn't sure of where the ball was, but at that time, there weren't exactly showing it on there, so I had to take my chance, and that was my call all the way."
