KEY BISCAYNE Kendall Sheffield Jersey , Fla. (AP) — proposal to refine the new rule that allows challenges involving pass interference, and may also announce locations to host upcoming drafts.Owners voted in March to allow interference calls or non-calls to be challenged by coaches and reviewed via replay as a one-year experiment.The tweak proposed this week would take the decision to review pass interference in the final two minutes of each half out of the hands of the officials. Reviews in the final two minutes would require a coach’s challenge, too.“The concern is how many stoppages will we end up with in the last two minutes,” Atlanta Falcons president and CEO Rich McKay said Tuesday. “One thing we do not want to do is be a game that has multiple stops in the last two minutes.”Under the rule adopted in March, in the final two minutes only officials in the booth can stop the game for reviews involving pass interference, as is the case with other reviewable plays.Owners are expected to vote on whether to let the NFL competition committee decide on changing the rule after it discusses the subject with the league’s coaches. McKay, a member of the committee http://www.falconsauthorizedshops.com/authentic-john-cominsky-jersey , said the group has conference calls with coaches scheduled for early June.Owners will also consider a proposal to exempt Hail Mary passes so they’re not reviewable. That would require the league coming up with the definition of a Hail Mary.“I actually don’t think it’s that hard,” McKay said. “It’s going to be from what yard line was it thrown, were there multiple receivers, how much time is left on the clock. But you want to get input from the coaches — what definition are you comfortable with?”Future host sites for the draft will also be discussed. The 2020 draft will be in Las Vegas, the new home of the Raiders.It’s uncertain whether owners will act on a proposed rule change that would require each team to have one possession in overtime. The change is being pushed by the Kansas City Chiefs, who lost last season’s AFC championship game without getting the ball in overtime because the Patriots won the toss, received the kickoff and scored a touchdown. ALAMEDA Qadree Ollison Jersey , Calif. (AP) — The Oakland Raiders filled two more holes on their depth chart Thursday by signing linebacker Brandon Marshall and running back Isaiah Crowell to one-year contracts.The moves are the latest ones in a roster overhaul by coach Jon Gruden and new general manager Mike Mayock after the team struggled to a four-win season in Gruden’s first year back on the sideline.Marshall joins recently signed Vontaze Burfict to give the Raiders two veterans at linebacker who will be counted on to upgrade a position that has been a weakness for years in Oakland. The two are expected to team with Tahir Whitehead as starters for coordinator Paul Guenther’s defense.Marshall has spent the past six years of his seven-year career in the AFC West in Denver. The Broncos declined to pick up his option earlier this offseason, making him a free agent.Marshall has been limited to 11 games in two of the past three seasons, missing time with a hamstring injury in 2016 and a bruised knee last season. Marshall started seven games for the Broncos in 2018, collecting 42 tackles without a sack or an interception as rookie Josey Jewell’s playing time increased.In 74 career games, the 29-year-old Marshall has 6 1/2 sacks, five forced fumbles, two interceptions and one fumble recovery.Crowell is expected to compete for playing time at an open position with Oakland’s two leading rushers last season Marquise Brown Jersey , Doug Martin and Marshawn Lynch, remaining as free agents. The leading returning back is Jalen Richard, who had 55 carries for 259 yards and is used more as a receiver.Chris Warren III will also be in the mix. He was impressive at times in training camp as a rookie last season but spent the entire year on injured reserve.Crowell ran for 685 yards and six TDs at an average of 4.8 yards per carry last season with the Jets. He has 3,803 yards rushing with 27 TDs and a 4.3 yard per carry average in five seasons with Cleveland and New York.The Raiders have been one of the busier teams so far this offseason, making a big trade for star receiver Antonio Brown, as well as signing free agents like Trent Brown, Lamarcus Joyner http://www.ravensauthorizedshops.com/authentic-jaylon-ferguson-jersey , Tyrell Williams, J.J. Nelson, Curtis Riley, Nevin Lawson and Burfict.
