NFL commissioner Roger Goodell said presentations this week by two stadium groups affiliated with NFL teams were “very exciting” and offered a “great deal of potential to be successful.”

St. Louis Rams owner Stan Kroenke is vying against a joint venture by the San Diego Chargers and Oakland Raiders for the right to call Los Angeles home again. All three teams have previously been based in the city.

Kroenke is planning a $1.8 billion stadium in Inglewood, and the Chargers and Raiders are working on a $1.7 billion venue in Carson. The Carson City Council unanimously approved the project on Tuesday, and new designs were presented to Goodell and the league’s relocation committee in New York.

On Friday, Goodell told the Associated Press Sports Editors, “We had presentations earlier this week that are very exciting — not just for a return but to continue being successful going forward.”

Meanwhile, a St. Louis task force hoping to keep the Rams (or lure another team) also presented plans for a $1 billion stadium near the Mississippi River.

—The Tennessee Titans agreed to terms of a one-year contract with wide receiver Hakeem Nicks.

Nicks, a first-round draft pick of the New York Giants in 2009, caught 311 passes for 4,622 yards and 27 touchdowns in five seasons with the Giants. After 1,000-yard receiving seasons in 2010 and 2011, foot and knee injuries slowed him in his final two seasons in New York.

He signed with the Indianapolis Colts last year and caught 38 passes for 405 yards and a touchdown.

—Dontari Poe, the Pro Bowl nose tackle of the Kansas City Chiefs, reportedly will remain with the team for at least another season.

The Chiefs have exercised the fifth-year option on Poe, keeping him under contract through 2016, NFL Media’s Albert Breer reported on Friday. The option year is worth $6.146 million.

The Chiefs selected Poe with the 11th pick in the 2012 draft, and the 6-foot-4, 350-pound lineman has been selected to the Pro Bowl the past two years while tallying 10.5 sacks from the middle of the line.

—Detroit Lions general manager Martin Mayhew confirmed the team intends to pick up the fifth-year option on left tackle Riley Reiff before the March 3 deadline.

Reiff has started 31 games over the past two seasons but has failed to live up to his status as the No. 23 overall pick and there had been some question about whether the Lions would exercise the $8 million option.

“Yes, we’re definitely going to do his fifth-year option and have him for a fifth year,” Mayhew said Friday. “We anticipate getting that paperwork done sometime soon.”

—New York Jets general manager Mike Maccagnan said he will explore the possibility of trading up in next week’s NFL Draft.

Speculation has the Jets, who have the No. 6 overall pick, setting their sights on Oregon quarterback Marcus Mariota.

Maccagnan, the Jets’ first-year GM who was speaking Friday at his pre-draft news conference in Florham Park, N.J., said he is hesitant to give away draft picks.

“We’re going to reach out to every team ahead of us to gauge, to get a value for what they’re looking for in compensation to move up in the draft,” Maccagnan said. “That doesn’t mean we’re actually trying to go up and get a player. But you hear what the market value is basically, and then what you do is see what unfolds with the first few picks and who is available. We’ll have that discussion when we get to the draft — if we want to move up in the draft.”

The Tennessee Titans hold the No. 2 pick and several teams are expected to be interested in acquiring it.

—Pittsburgh offensive tackle T.J. Clemmings has a stress fracture in his foot revealed during a recent workout with an NFL team, according to NFL Media’s Ian Rapoport.

The No. 29 prospect by NFLDraftScout.com, Clemmings (6 feet 5, 309 pounds) is considered a raw offensive tackle with a high ceiling. However, the stress fracture could affect his draft stock as there are several offensive line prospects with similar grades, including LSU’s La’el Collins (No. 23), Florida’s D.J. Humphries (No. 30) and Oregon’s Jake Fisher (No. 33).

According to the report, Clemmings was experiencing no pain and had no idea about the stress fracture.

—Restricted free agent running back Bobby Rainey signed a one-year, $1.54 million tender offer with the Tampa Bay Buccaneers.

The 5-foot-8, 212-pound Rainey was claimed off waivers in 2013 from the Cleveland Browns. He played in 15 games and started five for the Buccaneers last year.

The 27-year-old Rainey rushed for 406 yards and one touchdown on 94 carries and caught 33 passes for 315 yards and one touchdown in 2014. He is the team’s leading rusher the past two years, with 972 yards and six touchdowns on 244 carries.

—Safety Jaiquawn Jarrett, a restricted free agent, has signed his $1.54 million tender with the New York Jets, the team said Friday.

Jarrett, 25, started in seven of the 14 games he played last season, recording 41 tackles, 1.5 sacks, two interceptions, a forced fumble and a fumble recovery.

It was the most action Jarrett had seen since the Jets drafted him in the second round in 2011.

Friday was the deadline for restricted free agents to sign offer sheets with other teams.

—The Philadelphia Eagles, who signed running backs DeMarco Murray and Ryan Mathews last month, reportedly rescinded their contract tender to restricted free agent Chris Polk on Friday.

Polk, 25, is now free to sign with any team, according to Geoff Mosher of CSNPhilly.com.

Polk rushed for 172 yards and four touchdowns in a reserve role behind LeSean McCoy and Darren Sproles last season.

—Dallas Cowboys defensive end Greg Hardy was involved in a verbal altercation with backup defensive lineman Davon Coleman at the team’s facility and reportedly had to be separated by teammates.

FOX Sports first reported the incident Friday following an on-field argument that took place on the final day of the first week of the Cowboys’ offseason program.

According to FOX, the dispute between the defensive linemen arose from Hardy questioning Coleman’s effort during conditioning drills. The situation escalated when, according to a source, Coleman took a dig at Hardy’s domestic violence issues.

“(Coleman) called him a woman beater,” the source told FOX.

On Wednesday, Hardy was suspended 10 games without pay for “conduct detrimental to the league.”

—Dallas quarterback Tony Romo, making an acceptance speech for the Nancy Lieberman Lifetime Achievement Award, made a bold prediction to fans that “we’re going to win a Super Bowl next year.”

Romo gave a 10-minute acceptance speech earlier this month at the Dream Ball Gala in Dallas, according to the Dallas Morning News.

Romo described how he transformed from a player focused on individual goals to someone who now only cares about team accomplishments.

“This award is very meaningful to me, mostly because I get to be associated with this and to be associated with Nancy,” Romo said. “It’s incredible and I really appreciate you, and we’re going to win a Super Bowl next year. Thank you.”
