Maryland junior wide receiver Levern Jacobs and senior linebacker Alex Twine were charged with second-degree assault with the season opener a week away.
Twine was arrested and Jacobs, the Terrapins' leading receiver last year, was issued a summons on Thursday resulting from an April 19 incident. Twine was scheduled for an Oct. 3 appearance in Prince George's County District Court.
Maryland coach Randy Edsall did not indicate whether the two players might face team suspensions.
"We are aware of the situation and are in the process of gathering more information." Edsall told the Baltimore Sun. "We take these matters very seriously. We will have no further comment at this time."
Jacobs finished the 2013 season with 47 receptions for 640 yards. He is not expected to be a starter this season at one of Maryland's deepest positions.
Twine is a key special teams contributor who has made 12 career starts at linebacker. He enters this season as a top reserve at inside linebacker.
According to the Sun, Twine was arrested as a freshman in 2011 on a disorderly conduct charge.
The Terrapins open the 2014 season with James Madison next Saturday.
