Head coach Kyle Shanahan spoke to reporters on Tuesday morning at the NFL owners meetings and revealed that defensive backs coach Daniel Bullocks also sustained a torn Achilles during the game.
"[It occurred] about five minutes after Dre's," Shanahan told reporters. "I think it was when [S] Ji'Ayir [Brown] got the interception, he just jumped up and cheered, very similar to Dre's, and his Achilles went too."
Bullocks remained on the sideline and continued coaching throughout the game. Shanahan wasn't aware of the severity of the injury until his wife informed him the next morning.
"I just thought he hurt his ankle," Shanahan shared. "But by the time the game was over, he could barely walk. ... It was funny—the next morning, I woke up early, and my wife was telling me how Bullocks tore his Achilles. And I was like, 'No, it was Greenlaw.'
"And I got into the biggest argument with her. And then Bullocks got on the bus in a boot, and she's like, 'I told ya.'"
When asked about the unusual injuries and whether there was any contributing factor, Shanahan simply smiled and stated, "Nothing I want to get into," before acknowledging his frustration.
Bullocks has about the same recovery timeline as Greenlaw.
