Ravens’ Flacco plays waiting game while his injured back heals

OWINGS MILLS, Md. - Instead of playing football, Joe Flacco is playing the waiting game while his back heals.

The Baltimore Ravens quarterback missed the first two days of training camp, and there’s no telling when he will suit up.

Coach John Harbaugh said it might be a week, and Flacco agreed after his teammates walked off the field Friday.

“That’s what we’re all hoping for,” said Flacco, now in his 10th NFL season. “I want to be out there as soon as possible.”

Backup Ryan Mallett ran the first team, and the Ravens signed quarterback David Olson on Friday. Olson played under Harbaugh’s brother, Jim, at Stanford. He transferred to Clemson for his senior season and most recently played in the Champions Indoor Football League.

“We had to have another quarterback to get through practice and get through reps,”John Harbaugh said.
