The Jacksonville Jaguars will host top quarterback prospects Texas A&M's Johnny Manziel, Louisville's Teddy Bridgewater, UCF's Blake Bortles, Fresno State's Derek Carr and Eastern Illinois' Jimmy Garoppolo this week, according the multiple reports Tuesday.

Manziel is scheduled to fly to Jacksonville on Tuesday and will visit with the Jaguars on Wednesday, along with the four other quarterbacks, according ESPN.com. Two of the club's other top options with the No. 3 overall pick, Auburn offensive tackle Greg Robinson and Buffalo linebacker Khalil Mack, also are due to arrive Tuesday, according to NFL.com. On Wednesday, UCLA linebacker Anthony Barr will visit the Jaguars as well.

Manziel completed a visit with the Oakland Raiders on Monday and is slated to meet with the Houston Texans, who own the first overall pick, later this month, ESPN.com reported. Manziel visited with the New England Patriots last month and also met with Minnesota Vikings coach Mike Zimmer following his pro day on March 27.

---Representatives from the NFL Players Association met with league officials and club personnel on Tuesday with talks geared toward improving the workplace environment in the NFL.

The three-hour meeting focused exclusively on that topic, which became a necessary focus after a league investigation into the Miami Dolphins. Multiple players, including Richie Incognito, were found guilty of harassing teammate Jonathan Martin in what became a hotly debated and well-publicized magnification of locker room culture.

George Atallah, assistant executive director of external affairs, issued a statement, saying "Discussions between owners and players about a professional workplace were positive. We will continue to work together to set the highest workplace standards for everyone in the business of football."

---Washington Redskins defensive end Brandon Moore was suspended without pay for the first four games of the 2014 regular season for violating the NFL Policy and Program for Substances of Abuse, the league announced Tuesday.

Moore is eligible to participate in all offseason and preseason practices and games. He entered the NFL as an undrafted rookie in 2013, signing with the San Diego Chargers. Moore spent time on the practice squads of the Chargers and Denver Broncos before signing with the Chiefs after the season. The Chiefs released Moore in March and the Redskins claimed him off waivers.

The Redskins also announced that the team signed free-agent punter Blake Clingan to an undisclosed contract.

---New York Jets quarterback Michael Vick's past compelled a group at Change.org to start a petition to prevent him from attending training camp at SUNY Cortland.

"If we welcome Vick onto our campus, we are complicit in his crimes," the petition reads. "We are sending the message that, for money and publicity, we will turn a blind eye to the horrors of dogfighting."

The petition had nearly 2,000 signatures as of Tuesday morning and is addressed to the school president Erik J. Bitterbaum. Vick pleaded guilty to a federal dogfighting conspiracy charge in 2007 and served 19 months in prison. He signed with the Jets as an unrestricted free agent last month to compete with Geno Smith.

---The Buffalo Bills added some depth on the defensive line by agreeing to terms on a one-year deal with free agent Jarius Wynn, the team announced Tuesday.

Wynn, 27, played in 15 games (five with San Diego and 10 with Dallas) during the 2013 season and had 11 tackles and 2.0 sacks. He has appeared in 58 career games and totaled 45 tackles and 8.5 sacks in stints with the Packers (2009-11), Tennessee Titans (2012), San Diego Chargers (2013) and Dallas Cowboys (2013).

---Second-year quarterback Mike Glennon plans to push veteran Josh McCown for the starting job with the Tampa Bay Buccaneers in 2014.

Glennon started 13 games as a rookie and had 19 touchdowns and nine interceptions after replacing Josh Freeman atop the Tampa Bay depth chart. When coach Greg Schiano and general manager Mark Dominik were fired at the end of the season, Glennon expected competition. It came in the form of journeyman McCown, who played well in spot starter duty with the Chicago Bears during Jay Cutler's absence for groin and ankle injuries.

---The Atlanta Falcons signed safety Dwight Lowery and cornerback Josh Wilson, the team announced Tuesday.

Lowery (5-foot-11, 212 pounds) was originally selected by the New York Jets in the fourth round of the 2008 NFL Draft. He was traded to the Jacksonville Jaguars on Sept. 3, 2011. He has played in 68 career games, including 41 starts while totaling 217 tackles with 10 interceptions, three sacks and 45 passes defensed. In 2013, he started three games and posted six tackles with one fumble recovery before being placed on injured reserve and later released.

Wilson (5-9, 188) was originally selected by the Seattle Seahawks in the second round of the 2006 NFL Draft. He has played in 102 career games with 81 starts while totaling 399 tackles, 14 interceptions, 11 fumble recoveries, nine forced fumbles, five sacks and 71 passes defensed. Last season for the Washington Redskins, Wilson started all 16 games and posted a career-high 93 tackles, two sacks, two forced fumbles, one interception, and seven passes defensed.

---The Cincinnati Bengals on Tuesday re-signed wide receiver Dane Sanzenbacher, whom the club had tendered as a restricted free agent for 2014.
