Please note the updates at the bottom of this post.

I can only wish that today was April Fools Day, but it is not. On a day in which CB Eric Wright, LB Marcus Benard, and DE Brian Schaefering suffered injuries during the team's morning practice, linebacker D'Qwell Jackson might have suffered the most serious injury of the crop: a pectoral injury, according to Mary Kay Cabot of the Plain Dealer, during the team's evening session of practice on Tuesday:

It's not known if it's the surgically-repaired one or not. Jackson went in to be examined by the doctor at about 8 p.m. Jackson, who had been starting all camp at inside linebacker, walked off the field midway through practice very slowly and with his head down. He returned later in the session with a towel around his neck and looking sad.

One-by-one, players came up to express their concern. At one point, it looked like he pointed to his chest. He watched the final 15 minutes of practice from the sidelines, still looking down. Close friends such as Mike Adams talked to him, and he walked off the field with defensive coordinator Rob Ryan.

Based on Cabot's report, it's not looking good for Jackson, who suffered a torn pectoral injury last season too. If the injury is true, the Browns at least have two veterans they could insert in his place in Eric Barton or David Bowens. With that said, I was looking forward to seeing how a "motivated" Jackson would perform this season with more veterans around him.

UPDATE #1: Per Mary Kay Cabot on Twitter:

LB D'Qwell Jackson's pectoral injury isn't the surgically-repaired one, source told PD. Still no word on how serious it is.

UPDATE #2: Per Miami Herald's Jeff Darlington on Twitter:

Non-Dolphins related, but I hear D'Qwell's pectoral is not torn. Might not be that serious. He's waiting on a MRI to determine extent.

Darlington claims he is a high school friend of Jackson's, so that might explain why he'd have a scoop before the Cleveland media. I hope he's correct that Jackson's injury is not as bad as originally feared.
