Buffalo Bills defensive tackle Marcell Dareus was charged with reckless endangerment, reckless driving and participating in an illegal speed contest related to a drag racing incident in his Jaguar.

All three charges are misdemeanors in New York. Dareus was arraigned and released on his own recognizance by Hamburg (N.Y.) police for last week's drag-racing incident.

Head coach Doug Marrone said the 2013 Pro Bowl selection is not returning to the team's organized team activities while the team tries to get him "on the right track."

---Colin Kaepernick's agent is scheduled to meet with the San Francisco 49ers to discuss a long-term contract this week.

The Sacramento Bee said the meeting will take place this week in Santa Clara, just after the 49ers gained additional cap space after the June 1 transaction designate date. The 49ers want to get a new deal done before the start of the season, but the two sides are reportedly not close from their most recent sessions.

Head coach Jim Harbaugh lobbied publicly for Kaepernick to get a long-term contract in line with the top starters in the NFL, which could net him between $18 million and $21 million annually.

--The 49ers announced the signing of linebacker Blake Costanzo to a one-year deal. Costanzo is a seven-year NFL veteran, and played in all 16 games for the Chicago Bears last season primarily as a special teams ace. Costanzo, 30, also appeared in 18 games including playoffs for the 49ers in 2011.

Guard Al Netter was waived to create a roster spot for Costanzo.

---In need of reinforcements at linebacker, the Arizona Cardinals signed veteran Ernie Sims to a one-year contract on Tuesday.

Sims' addition comes shortly after Daryl Washington was suspended for the 2014 season because of a violation of the league's substance abuse policy.

The 6-foot, 233-pound Sims spent the past two seasons with the Dallas Cowboys. He was drafted in the first round in 2006 by the Detroit Lions and started 56 games before going to the Philadelphia Eagles, the Indianapolis Colts and the Cowboys.

---The Philadelphia Eagles reached agreement on a three-year extension with offensive lineman Allen Barbre on Tuesday.

The contract now runs through the 2017 season. Barbre signed his original two-year deal with the Eagles in January 2013. The six-year veteran has made seven starts and played in 47 games with the Eagles, Green Bay Packers, Miami Dolphins and Seattle Seahawks.

---Tight end Jermichael Finley, a free agent who suffered a neck injury with the Green Bay Packers last season, visited the New England Patriots last week.

Finley was not offered a contract but continues to generate interest on the open market as teams do their due diligence to gauge his recovery from the potentially career-threatening injury. The Seattle Seahawks showed interest early in free agency.

Finley could still return to the Packers but should he not play at all this season, he said he has a $10 million insurance policy -- about $3 million more than his salary with bonuses last season -- that would kick in.

---Tim Tebow is gainfully employed by the SEC Network, but broadcasting would not qualify as the former Heisman Trophy winner's dream job.

That's why Tebow, a first-round pick of the Denver Broncos who last started regularly in the NFL in 2011, is staying in shape and keeping his phone close by.

"I'm training every day and feel like I'm the best that I've ever been," Tebow told The Tennessean. "I still love it, love playing, talking about it, and I'm just excited about whatever the future holds. Who knows what could happen? But I'm excited about it, though."

---Rookie linebacker Lamin Barrow, a fifth-round pick in the 2014 draft, signed a four-year deal with the Denver Broncos.

Barrow was the 156th overall pick and wore many hats for LSU as a linebacker/safety hybrid. He played 51 career games (28 starts) for the Tigers and totaled 230 career tackles, 14 1/2 tackles for loss and 1 1/2 sacks. He was a second-team All-Southeastern Conference selection as a senior in 2013 after leading LSU with 91 tackles.
