Baltimore Ravens quarterback Joe Flacco will reportedly miss the start of training camp because of a disc issue in his back.
On Wednesday, Ian Rapoport and Tom Pelissero of NFL Network reported he is out "at least a week or two" and is preparing to miss as much as three to six weeks.
Jeff Zrebiec of the Baltimore Sun first reported the injury but said that back soreness may limit his repetitions or cause him to miss a few practices.
Flacco nursed a minor shoulder injury in 2016, but the ailment didn't force him to miss any games a season after he tore his ACL.
