Levi's Stadium may not generate a lot of noise, but one of the hotels nearby certainly did.
An alarm went off at the Eagles team hotel shortly before 2 a.m., according to players' Twitter accounts.
“Which cruel cruel Niners fan pulled the fire alarm at our hotel?!” linebacker Emmanuel Acho wrote on Twitter.
After 17 minutes of din, quarterback Matt Barkley wrote, “Make it stopppp.”
Last year, the Dolphins received a 3 a.m. wake-up call courtesy of an alarm-puller in Buffalo. They lost later that day 19-0.
The Eagles are 3-0 but are 3- or 4-point underdogs to the 1-2 49ers. And that was before they were rudely awakened in Santa Clara.
