San Francisco 49ers head coach Jim Harbaugh tried his best not to comment on the replacement officials that officiated his team's preseason game against the Houston Texans on Saturday, but ended up saying enough to possibly earn a call from the league office.

Teams and coaches are not to speak on the replacement officials but after letting the press know of that fact during the first portion of his postgame presser, Harbaugh found time to still get in what he was truly feeling about the officials' performance, according to Matt Maiocco of CSNBayArea.com.

"Big interference call in third quarter was some big yardage on that drive. I don't know. It's interesting. I don't have the pulse on this game," Harbaugh said. "What was it exactly? Us? Them? Some crazy, wild calls. Were they accurate? Weren't they? We'll see. I have a headache, though. I have a darned headache. A lot of them didn't seem like they were in the ballpark."

With replacement officials looking like they'll be around through the first week of the season, the NFL and its coaches will have to try to keep the peace for as long as they can.
