KNOXVILLE, Tenn. (AP) - Tennessee linebacker A.J. Johnson and defensive lineman Danny O'Brien have been arrested on alcohol-related charges and resisting arrest, authorities said Sunday.
The Knox County Sheriff's Office says 22-year-old Johnson and 20-year-old O'Brien were taken into custody late Saturday.
Johnson, a first-team all-Southeastern Conference selection last season, was charged with purchasing alcohol for a person underage and resisting arrest. O'Brien, a reserve nose tackle as a redshirt freshman last season, was charged with criminal impersonation, resisting arrest and underage consumption of alcohol.
Former Tennessee linebacker Dontavis Sapp, 22, also was arrested for resisting arrest and purchasing for a person underage.
All three have been released.
Tennessee coach Butch Jones said in a statement released by the university that he's aware of the situation and is gathering facts.
''We have very high standards and expectations within our football program at the University of Tennessee, and appropriate action will be taken,'' he said.
Johnson made a team-high 106 tackles last fall in his third season as a starter. He had 138 tackles in 2012 and ranked fourth among all Football Bowl Subdivision players with 11.5 tackles per game. Johnson announced last month he would return for his senior season rather than entering the NFL Draft.
O'Brien made 12 tackles and played in all 12 games in a reserve role as a redshirt freshman last season. Sapp closed his career last fall by starting 12 games and making 66 tackles.
