Ravens running back Collins misses practice with calf issue

OWINGS MILLS, Md. — Starting running back Alex Collins did not participate in Wednesday’s walk-through as the Ravens continued preparations for their Week 13 showdown with Detroit.
The second-year back finished Monday’s game without any apparent incident, but he is dealing with a calf injury, according to Wednesday’s injury report. Collins rushed for 60 yards and a touchdown on 16 carries in the 23-16 win over Houston and was on the field for the final series of the contest.
Cornerback Marlon Humphrey (thigh), left tackle Ronnie Stanley (knee), and linebacker C.J. Mosley (ankle) were listed as limited participants in the walk-through practice. The rookie Humphrey was limited to just seven snaps against the Texans and missed time in the preseason because of a hamstring injury.
“He had a little tweak in there. He has been battling some leg issues,” said head coach John Harbaugh after Monday’s game. “I just decided let’s play it safe. That’s the good thing about having some depth, but we want him out there.”
Meanwhile, the Lions listed standout quarterback Matthew Stafford as a full participant, which should eliminate any remaining doubt about his status for Sunday. He hurt his ankle in his team’s Thanksgiving loss to Minnesota, but he was able to return to the game.
Detroit running back Ameer Abdullah (neck) and recently-added pass rusher Dwight Freeney did not participate in Wednesday’s practice.
