New Mexico junior quarterback David Vega has been suspended from the team indefinitely.
The suspension was announced Tuesday by Lobos coach Bob Davie, who says Vega was arrested early Sunday by Albuquerque police.
Details of the arrest weren't immediately available.
Davie says that until he's satisfied that he has all the facts, he won't make a decision on Vega's return to the program.
Vega is the second Lobos player suspended in two days.
On Monday, Davie announced that sophomore defensive back Devonta Tabannah has been suspended and won't play in Saturday's season-opening game against Southern.
Davie said the suspension was for violating team rules, but he wouldn't elaborate.
However, police told KRQE-TV that Tabannah was arrested Sunday in downtown Albuquerque on suspicion of drunken driving.
