OWINGS MILLS - Inside linebacker Jameel McClain's injured spinal cord remains a concern, enough so that there is still no clear timetable for when - or even if - McClain will be cleared to resume football activities.
Ravens coach John Harbaugh is yet to rule out the possibility of McClain playing this season, but it appears less and less likely with each update regarding McClain and his spinal cord.
McClain was injured against the Washington Redskins in December - the injury diagnosed as a spinal cord contusion.
Harbaugh said Tuesday that doctors originally anticipated McClain's spinal cord being healed by this point but that the injury is healing "a little slower than we had hoped."
Harbaugh also said Tuesday that McClain was scheduled to undergo more tests yesterday. Based on what Harbaugh said today, the tests didn't provide the Ravens with any more optimism regarding McClain and his availability for this season.
"It's just when you look at the MRI and you see what's on there, there's no denying the fact that it's not safe for him at this time," Harbaugh said, "so there's no way that we are going to put him out there until it clears up.
McClain has been a starting inside linebacker for Baltimore the last three seasons.
Veteran Daryl Smith, who the Ravens signed last month, appears entrenched as a starter at one of the Ravens' two inside linebacker spots. If McClain ultimately isn't able to play this year, Albert McClellan, Josh Bynes and second-round pick Arthur Brown will be the primary three competing for the other starting inside linebacker job.
Many predict Brown will eventually win the spot, but McClellan was the one running next to Smith with the first-team defense during the Ravens' first full-team practice of training camp today.
McClellan, who has seen time at both inside linebacker and outside linebacker for Baltimore during the last three years, started 11 games last season.
