Clarence Brooks and Mike Pettine have been retained by the Ravens as assistant defensive coaches.
Harbaugh mistakenly thought that the team had made the move public.
"Has that been announced yet? Well, we're announcing it now," Harbaugh said with a chuckle. "That happened today. Clarence Brooks is going to be on board, and everybody knows what a great job he's done here."
Ryan acknowledged that Pettine also would return in some capacity. Pettine, who coached the outside linebackers, could succeed Jeff FitzGerald as linebackers coach. FitzGerald joined the Cincinnati Bengals as their linebackers coach last week.
"He'll definitely be involved with our linebackers," Ryan said of Pettine, deferring questions about details to Harbaugh. "He's a rising star in this game, and we're really proud and fortunate to be able to keep Mike."
Perhaps the biggest question mark is in the secondary. Dennis Thurman coached the defensive backs the previous four seasons but there has been some talk that secondary coach Mark Carrier deserves a promotion.
Ryan: Keep Suggs -- Ryan said he would like to see the Ravens sign linebacker Terrell Suggs. Suggs, who is only 25, will become an unrestricted free agent in several weeks and likely will draw a number of suitors. If the Ravens and Suggs can't agree on a new contract, the team might attach its franchise tag to Suggs. "I would've gone in the opposite order," Ryan said. "I would've given money to Suggs to keep and then thrown me a bone afterwards. ... He's a rare player and it's a lot easier to win with him than it would be to play against him, that's for sure."
On the air -- The Ravens extended their radio deal with 98 Rock (97.9 FM) and WBAL (1090 AM) with a four-year contract that runs from 2008 through 2011 and also moved their preseason games to WBAL/Channel 11, the club announced along with Hearst, the corporation that owns the stations. The 2007 season was the team's second on 98 Rock and WBAL Radio. Channel 11 will also carry other Ravens-related programming, and Mid-Atlantic Sports Network will continue to televise weekly in-season shows, such as Wired and Ravens Report.
