Potential 49ers defensive coordinator candidate Jeff Ulbrich was hired by the Atlanta Falcons for the same role.

Brant Boyer was announced Monday as the 49ers’ new special teams coordinator, a role he held the past nine season with the Jets, where he overlapped and worked under coach Robert Saleh, who was re-hired Friday as the 49ers’ defensive coordinator.

The Atlanta Falcons officially introduced their new defensive coordinator, Jeff Ulbrich, on Monday morning. The 47-year-old coach was welcomed with a press conference where the media had the chance to ask questions and get to know the newest addition to the Falcons' coaching staff.

Now back for his second stint calling plays for the Atlanta Falcons' defense, coordinator Jeff Ulbrich is different -- but similar in important ways.

The 49ers just missed out on a quality defensive coordinator candidate. Jeff Ulbrich has agreed to become the Atlanta Falcons' next defensive coordinator.

The San Francisco 49ers’ list of potential defensive coordinator candidates appears to be short, and it got shorter Saturday when NFL Media’s Tom Pelissero reported the Atlanta Falcons were set to hire Jeff Ulbrich as their new defensive coordinator.

The San Francisco 49ers search for a new defensive coordinator has not necessarily gotten off the ground. Robert Saleh is seen as the top candidate.

The San Francisco 49ers will look ... Saleh coming back to the Bay is a long shot. And now, the 49ers may have lost out on their No. 1 backup plan, Jeff Ulbrich. NFL Network's Tom Pelissero ...

The 49ers on Monday hired former New York Jets assistant coach Brant Boyer as special teams coordinator. Boyer replaces Brian Schneider, who served as 49ers’ special teams coordinator for the past three seasons. Schneider was fired the day after the 49ers finished the regular season with a 6-11 record.

The Bucs’ misfortune would be the 49ers’ gain since Saleh appears lined up to take the 49ers DC job if he doesn’t land a head coaching gig. He also had interviews lined up with the Raiders and Dallas Cowboys, but his name hasn’t been tied as heavily to those clubs as it has to the Jaguars.

One of those names is interim head coach Jeff Ulbrich. Originally the defensive coordinator but promoted to the role after New York fired Robert Saleh, Ulbrich went 3-9 at the helm and failed to turn around the Jets season. After interviewing for the head coaching job last week, Ulbrich didn't want to wait to be told no by New York.
