Week suspension for Collins

Arkansas running back Alex Collins, center, calls the Hogs during overtime Tuesday, Jan. 14, 2014, in Bud Walton Arena in Fayetteville.

— Arkansas running back Alex Collins is the latest football player to be suspended this off-season.

Razorbacks coach Bret Bielema announced the suspension during a news conference Monday to introduce new defensive coordinator Robb Smith. Collins' suspension is for one week and isn't anticipated to include loss of practice time when spring practice begins next month.

"Alex will be out this week, see how he handles this week and get ourselves moving forward," Bielema said. "You'll probably see that he is not going to be as active on Twitter and everything else as well. He's been removed from all social media until further notice. He's a tremendous young man that has to step up in certain areas to get where we want to be and I think he'll do that."

Collins is the fourth player Bielema said has been given a week suspension during the team's off-season workouts. Scholarship running back Korliss Marshall and walk-ons Bubba Crouch and Nathan Williamson were suspended last week but have rejoined team activities, Bielema said.

"We're in an eight-week window of winter conditioning," Bielema said. "Four weeks have gone by, and if you're not moving forward you're not helping us at all. We need to see guys make physical gains, strength gains and then definitely in the academic area. And if somebody is lacking in those three areas, it's pretty easy for me to remove the football side of it until they figure it out, because that usually makes kids a little bit more accountable."

Collins rushed for 1,026 yards and 4 touchdowns in 2013 and was named the Southeastern Conference Freshman of the Year by The Associated Press.
