Bears re-signed TE Dante Rosario.
Rosario was originally signed two weeks ago, then released on Monday. Presumably, the run blocker will now remain on the roster through the rest of the offseason program.
Lions signed DE/LB Darryl Tapp, formerly of the Redskins.
Tapp, 29, is a special teamer and reserve edge player. He does not figure to push for significant defensive playing time barring multiple injuries.
Colts signed C/G Phil Costa, formerly of the Cowboys.
Costa, 27 in July, appeared to be an ascending player in Dallas before falling out of the coaching staff's favor in 2013 as the Cowboys used a first-round pick on Travis Frederick. We wouldn't rule out Costa starting at center for the Colts, or at least giving Khaled Holmes a serious run for his money.
Chargers agreed to terms with QB Kellen Clemens, formerly of the Rams, on a two-year contract.
With Charlie Whitehurst headed to the Titans on a two-year deal, Clemens will replace Checkdown Charlie as Philip Rivers' backup. Clemens was surprisingly serviceable in nine starts in place of Sam Bradford last season, but was still well short of effective. He's a game-manager who can keep teams in games with a strong running game. Clemens is a major upgrade on Whitehurst, who's one of the league's least-effective backups.
Titans signed QB Charlie Whitehurst to a two-year contract with a max value of $8 million.
Whitehurst, 32 in August, spent last season with new Titans coach Ken Whisenhunt in San Diego. The journeyman could have an outside chance at pushing Jake Locker for playing time, and expedite Ryan Fitzpatrick's release. Whitehurst holds a career 54.2 completion rate and 3:4 TD-to-INT ratio across four NFL starts. He's failed to impress every single time we've seen him.
Cardinals waived LB Dontay Moch.
The 2011 third-rounder was promoted from the practice squad last September. He appeared in only four games, though he managed to register a sack. Moch has been highly injury prone through the first three years of his career.
Texans TE Garrett Graham says new coach Bill O'Brien plans to use him as a "move tight end, an H-back."
"I'm excited about that," said Graham, who received $11.25 million via his new three-year contract. Graham's athleticism pales in comparison to Aaron Hernandez's, but O'Brien was on New England's staff during Hernandez's finest years as an H-back and move tight end. It sounds like the Texans are penciling Ryan Griffin into the "Gronk" role, though things could change on draft weekend.
Free agent Anthony Dixon has left his Titans visit without a contract, and will visit the Bills next.
Dixon would be an intriguing addition in run-heavy Buffalo, but the Bills appear unlikely to release Fred Jackson heading into the final year of his contract. That means that, as he was in San Francisco, Dixon would be no higher than third on the depth chart. He'd be an upgrade on Tashard Choice.
