The NFL announced a two-game suspension for Aaron Jones for violation of the league's substance abuse policy. The Packers running back said on Twitter he takes responsibility  Alex Goligoski Jersey , regrets his mistake and accepts the suspension.

"The NFL announced my suspension today," Jones wrote. "I accept it, take responsibility for it, and regret the mistake that I made during the 2017 season which led to the punishment. I've let down my family, teammates  Youth Dustin Byfuglien Jersey , coaches, the Packers' front office, Packers' fans, UTEP, UTEP fans  Mark Scheifele Jersey , and the communities of El Paso and Green Bay. I apologize to all impacted and promise that this will never happen again and when I touch the field again it's going to be special."

Jones, 23, rushed for 448 yards and four touchdowns last season as a rookie.

He can participate in training camp and the preseason. His regular-season debut can't come until Week 3, though.

The New York Giants have signed safety Michael Thomas, who spent the last five seasons in Miami.

The move reunites Thomas with Lou Anarumo  Wayne Simmonds Jersey , his position coach with the Dolphins. Anarumo joined coach Pat Shurmur's staff as the defensive backs coach.

Thomas is the seventh defensive player added by New York in the last two weeks, joining linebackers Alec Ogletree and Kareem Martin, defensive backs Teddy Williams, Curtis Riley and B.W. Webb; and defensive tackle Josh Mauro.

Thomas played in 13 games last season with two starts. He had 16 tackles, plus seven special teams tackles.

Thomas entered the NFL with San Francisco in 2012 as a free agent out of Stanford. He spent that season and most of 2013 on the practice squad.
