Jaguars sign ex-Vikings RB Thomas, who is suspended 3 games

The Jacksonville Jaguars have signed former Minnesota Vikings running back Roc Thomas, who is suspended for the first three games of the regular season for violating the NFL's substance abuse policy.

The Jaguars are down two running backs - rookie Ryquell Armstead (quadriceps) and veteran Thomas Rawls (hamstring) - heading into joint practices and their preseason opener in Baltimore. Current Jaguars offensive coordinator John DeFilippo coached Thomas in Minnesota.

Thomas was sentenced to three years of probation in May after pleading guilty to felony marijuana possession. He was arrested in January after police found 143 grams of the drug in his apartment. Officers also confiscated $15,802 and a .45-caliber handgun, according to a criminal complaint.

Thomas appeared in five games for the Vikings last year as an undrafted rookie from Jacksonville State, where he finished his college career after playing two seasons at Auburn.

He can participate in preseason practices and games. If he makes the team, he would be eligible to return Sept. 23.

Jacksonville waived cornerback Jocquez Kalili on Sunday to make room for Thomas on the 90-man roster.
